PERKONGSIAN MAKLUMAT BERKAITAN FOTOGRAFI Nikon D700 verdict


Nikon impressed us all with its D300 and D3 bodies, but many believed a combination of the two could yield something even more special. Now there's no need to wonder. By essentially squeezing the D3’s full frame and high ISO quality into the D300’s more portable and affordable form factor, Nikon’s done just that with the new D700.
As such it’s hard not to be impressed by the D700’s handling, performance and feature-set. After all, it inherits a powerful 51-point AF system, high resolution 3in VGA monitor with Live View and superb 1005-pixel metering system, along with an HDMI port for connection to HDTVs. All this along with exactly the same full-frame sensor as the flagship D3 has been squeezed into a dust and moisture resistant body that’s closer in size and weight to the semi-pro D300.

The image quality is excellent as you’d expect, matching the D3’s high sensitivity performance. Switch the D700 to its highest sensitivity and you’ll see noise speckles like any other camera, but you have to remind yourself this is now operating at a whopping 25600 ISO. Turn the D700 down to 1600 or even 3200 ISO – a point where most DSLRs are still delivering noisy or smeared images – and you’ll be greeted by remarkably clean and usable results. It really is an amazing experience to confidently shoot at such high ISOs knowing the result won’t be compromised.

In-camera JPEGs taken with the default settings can sometimes look a little soft, but this is easily corrected by applying a little additional sharpening. For the best results though, shoot in RAW with the 14-bit option. Even using Capture NX's default settings, the results are much crisper than in-camera JPEGs, without losing any of their very natural quality.
Like other full-frame bodies, it’s also a delight to see lenses deliver the same field-of-view they would with 35mm film SLRs. Ultra-wide angle lenses like the excellent Nikkor AF-S 14-24mm really come into their own on full-frame bodies, and the large viewfinder is also a joy to use.
The benefits of full-frame sensors are often tempered though by more apparent vignetting and edge aberrations from lenses, but the D700’s in-camera corrections really do reduce their impact. That said, you will need a lens that's sharp to the edge of the full-frame to make the most of the D700. DX lenses will work on the D700, but as explained on our features page, you'll either need to work in a cropped 5 Megapixel mode, or suffer greatly reduced quality towards the edges. So if you do go for the D700, you'll really need a collection of (potentially expensive) full-frame compatible lenses to do it justice.
While it’s easy to simply describe the D700 as a D300 with the D3 sensor though, there’s a number of additional differences and enhancements worth noting. The card door latch may have been sacrificed for the new Info button, but it does at least now offer direct access to many settings which were otherwise buried across various menus.
The Live View implementation may at first appear the same as the D300, but graphics like the alignment grid are now more easily switched on and off using the Info button. The D700 has also inherited the D3’s handy Virtual Horizon feature, and made it more useful by offering it in Live View (an enhancement D3 owners can also now enjoy with a firmware update). You can additionally assign Live View to the Function or DOF preview buttons, thereby allowing you to select the self timer or continuous shooting from the release dial.

Nikon D700 - top view


Much has also been written about how the D700’s continuous shooting and viewfinder are inferior to the D300, but that’s not looking at the whole story. The D300 may have 6fps to the D700’s 5fps, but unlike the D300, the D700 doesn’t slow down when shooting 14-bit RAW files. And while the effective buffer of both cameras reduces at higher sensitivities, the D300 does it at 800 ISO compared to the D700 at 3200 ISO.
And sure, the D300’s viewfinder may sport 100% coverage to the D700’s 95%, but the latter’s full-frame penta-prism means the overall view is much larger and ultimately preferred – remember you can still switch to Live View if you need to check 100% coverage.

So what’s not to like? Well it’s a shame there’s still no Live Histogram in Live View, and annoying that camera control and decent RAW processing software aren’t included as standard. Indeed it should be embarrassing to Nikon that all of this is available even on Canon’s entry-level DSLRs. We’d also prefer if GPS units could connect directly to the D700’s USB port rather than via a proprietary cable accessory. And while assigning Live View to the Function or DOF preview buttons may allow you to select drive options from the release mode dial, we’d ultimately just prefer a dedicated Live View button.
This is all just nit-picking though. The Nikon D700 is quite simply a superb piece of kit, but there is of course one big factor we’ve not yet mentioned: price. The D700 may be cheaper than the D3 and discounts will see it drop further, but the fact is the launch price is around double that of current D300 bodies. We’ve seen this before with the Canon EOS 5D: full-frame sensors are simply very expensive to produce and you’ll be paying a considerable premium for one. In order to make the most of it, you'll also need to couple the D700 with quality full-frame compatible lenses, and they don't come cheap either.
Full-frame is undeniably a desirable technology to have, but only you can decide if it’s worth paying the extra. After all for the same money as a D700 body you could get yourself a D300 and an AF-S 14-24mm lens, or a cheaper optic and a nice trip to try it all out on. And if you shoot at low sensitivities, the image quality - as seen on our results pages - is essentially the same.
Of course you could alternatively be coming from the opposite direction and find the D700 a relative bargain compared to the D3, but with the form factor and features being so close to the D300, it’s impossible not to make the comparison and realise the cost associated with that larger sensor area. So before wrapping-up let’s take one more look at the differences between the three top Nikons along with Canon’s ageing EOS 5D.

Compared to Nikon D300

Nikon D300


The new D700 may appear to trump the D300 with its full-frame sensor, but there’s actually a number of reasons to prefer the older model. Most importantly, you’ll enjoy all of its 12 Megapixels with DX-format lenses, compared to using just five from the D700’s larger sensor. Many wildlife and sports shooters will prefer this higher pixel density, and you’ll also experience less issues with vignetting or reduced sharpness towards the corners when using FX-compatible lenses.
The D300 is also a little faster as standard, shooting JPEGs or 12-bit NEFs at 6fps to the D700’s 5fps. The D300’s viewfinder may not show the expanse of full-frame, but it does boast 100% coverage to the 95% of the D700. The D300 is also a little smaller (mostly shorter due to the smaller penta-prism), 170g lighter, and while both bodies are dust and moisture resistant, the D700’s sliding memory card door feels cheaper than the D300’s lever-operated mechanism.
In its favour, the D700 of course has the larger, more sensitive sensor, but there’s other advantages too. The continuous shooting doesn’t drop in speed when shooting 14-bit NEFs, and the buffer doesn’t shrink until you’re using sensitivities two stops higher. The viewfinder may not deliver 100% coverage, but it’s still comfortably larger and sports a built-in curtain, while the camera additionally includes the Virtual Horizon feature and an Info button giving quick access to many settings.
The big difference though is price, with the D700’s sensor adding a significant premium – indeed the D300’s online prices were half that of the D700’s launch price, and even when discounts arrive there’ll still be a significant difference. Ultimately while the D300 may not match the D700’s high ISO performance nor have features like the Virtual Horizon or fast 14-bit RAW shooting, it remains one of the most powerful and compelling semi-pro DSLRs on the market. See our Nikon D300 review for more details.

Compared to Nikon D3

Nikon D3


The D700 may have cherry-picked the key specifications of the D3 including its full-frame sensor, but Nikon’s flagship model still has much to offer. Physically the D3 features a built-in portrait grip and a larger battery as standard. The continuous shooting is also almost twice as fast at 9fps to the D700’s 5fps. Both the D3 and D700 have large full-frame viewfinders, but the D3 boasts 100% coverage, a 5:4 aspect ratio mode, and crucially for pro shooters, a shutter block that’s rated to 300,000 cycles – twice that of the D700 (and D300).
That said, the D3 misses out on the anti-dust features of the D700, and it doesn’t have a popup flash, although the latter can equally be seen as a physical weak-point. The D700 is also smaller and lighter, but again pros may see the heft of the D3 as preferable. Finally, the D3 is comfortably more expensive than the D700. Most pros will easily justify paying the extra, but anyone only wanting the higher ISO performance of a full-frame sensor will be better-served by the D700.

Compared to Canon EOS 5D

Canon EOS 5D


With all the excitement surrounding Nikon’s D700, it’s important to remember Canon’s EOS 5D offered 12 Megapixel full-frame performance at an ‘affordable’ price almost three years earlier. Both it and the D700 offer essentially the same resolution and the benefits of a full-frame sensor along with roughly the same-sized viewfinders, but the best part of three years age difference gives the Nikon a significant advantage in terms of modern features.
The D700 shoots faster at 5fps to the Canon’s 3fps, has a 51-point AF system compared to nine on the 5D, and a much higher 25,600 ISO maximum sensitivity to the 5D’s 3200 ISO. It also boasts a larger and more detailed 3in VGA screen (2.5in 230k on the 5D), supports Live View (complete with contrast-based AF and a Virtual Horizon), has more sophisticated metering, 14-bit RAW files, a viewfinder grid without the need to buy a separate focusing screen, an HDMI port, and is compatible with lenses designed for cropped bodies (albeit with a reduction in resolution to 5 Megapixels). Physically they’re roughly the same size, although the 5D is 185g lighter, but lacking the D700’s degree of weather-sealing.
In short, the D700 comfortably out-features the EOS 5D, as you’d expect for a body which is almost three years newer. But in the 5D’s defence, it sports the same resolution and the same sized sensor, while three years of sales has seen the body fall to around 60% of the D700’s launch price. Judging from our results, the quality still stands-up too. Looking beyond the body to the system as a whole, it's also important to note most decent full-frame Nikkor zooms are currently pricey f2.8 models, whereas Canon additionally offers a number of smaller, lighter and more affordable f4 options.
It’s widely believed a successor to the 5D will also arrive by the end of 2008 which many expect to match or exceed the D700’s specifications, but if you can live without the new features and fast continuous shooting, the EOS 5D remains a compelling option and the most affordable full-framer to date. See our Canon EOS 5D review for more detail

ikon D700 final verdict

Nikon has been very cunning with the feature-set of the D700, taking the key specifications of the D3, and only leaving those which would affect a small and generally pro audience – who probably already have a D3 anyway. So by keeping the core image quality of the D3 and squeezing it into a smaller, lighter and cheaper body with the addition of a popup flash and anti-dust features, Nikon’s created a highly compelling full-frame DSLR.
It does however leave the question of a very high resolution body, as Nikon’s top three DSLRs now all feature ‘just’ 12 Megapixels. This may be sufficient for most photographers, but pros or anyone shooting for high-end libraries demand more. Canon has long offered the 1Ds Mark III with 21 Megapixels and the long-awaited EOS 5D successor is bound to make a comfortable leap beyond its current 12 Megapixels.

Many industry watchers are expecting to see a high resolution ‘D3x’ by the end of 2008, probably featuring Sony’s recently announced 24 Megapixel full-frame sensor in a D3 form factor. How this will perform – should it even exist – is anyone’s guess, but if you’re thinking of spending big bucks on the D700, it’s worth speculating Nikon’s next move in the high-end DSLR market.
If you’re happy using a rival brand, there’s also Sony’s flagship Alpha – most likely with that 24 Megapixel sensor, built-in stabilisation and an aggressive price tag – along with Canon’s long-awaited successor to the EOS 5D to consider, the latter almost certainly offering more than 12 Megapixels. Both are again expected by the end of 2008.
But today we have the Nikon D700 which is by far one of the most impressive DSLRs we’ve tested. Indeed, beyond the minor nitpicking mentioned above, there’s really little we can criticise it on. Depending on your viewpoint it either represents a smaller, lighter and more affordable way to enjoy the D3’s superb image quality, or equips the D300 form factor with a significant step-up in high-sensitivity performance. That’s a win-win whichever way you look at it and if you fall into either camp you’ll be absolutely delighted by the D700.
Ultimately like the Canon EOS 5D almost three years before it, you have to ask yourself if you really need full-frame, as it still adds a very high premium over cropped-frame models like the D300. You might take one look at our High ISO Noise results and know that's exactly what you want, or you may equally be underwhelmed by the differences for the money. You should also look carefully at the full-frame lens options that are available, as this can result in a significant additional investment.

If you don’t need full-frame then simply go for models like the D300 and relax in the knowledge its resolving power at low sensitivities is essentially the same. But if you can justify the extra outlay for high ISO performance and lack of field reduction, then the D700 is a superb choice. And again while it is much more expensive than the D300, it remains comfortably cheaper than the only other full-frame option from Nikon – so at least we’re heading in the right direction.
So with the D700 Nikon further broadens its impressive DSLR line-up and continues to throw down gauntlet after gauntlet to Canon, making its arch rival look complacent in some categories. Canon simply has to respond, but until then there’s few independent observers who wouldn’t consider Nikon now having number one billing in DSLRs.

18.1 Megapixel full-frame CMOS sensor 
The EOS-1D X features a newly developed Canon full-frame 18.1 Megapixel CMOS sensor that's designed from the ground up to create high resolution, perfectly detailed images with unprecedented speed and clarity. A full 24 x 36mm, the sensor captures 5184 x 3456 large individual 6.95 µm pixels and has a much-improved S/N ratio resulting in better images from the start. A new photodiode structure with an increased photoelectric conversion rate increases the sensor's sensitivity by approximately 2 stops over previous models, meaning higher ISOs with the lowest noise of any EOS digital camera. And a 2-line 16-channel simultaneous signal readout means speeds of up to 12 fps (RAW + JPEG) and even 14 fps (Super High Speed Mode) are possible!



14-bit A/D conversion, wide range ISO setting 100-51200 (L: 50, H1: 102400, H2: 204800)
The EOS-1D X not only offers 14-bit signal processing for excellent image gradation, it delivers higher standard and expanded ISOs, and a score of new options to enhance shooting in varied and fast-changing lighting situations. With a standard range of ISO 100-51200, the EOS-1D X represents a 2-stop increase in sensitivity over previous cameras. Thanks to the improved signal-to-noise ratio of the new sensor and powerful noise reduction, the EOS-1D X can shoot at expanded sensitivities down to ISO 50 (L) and up to 102400 (H1), and even 204800 (H2)! Beyond the obvious advantages of its wide ISO range, the EOS-1D X has automatic ISO settings, found on the dedicated ISO menu. Minimum and maximum ISO settings can be specified, as can a user-defined range, plus full auto and manual.





Dual DIGIC 5+ Image Processors for enhanced noise reduction and blazing processing speed
For a whole new level of performance, the EOS-1D X uses Dual DIGIC 5+ Image Processors that include four 4-channel A/D converter front-end processing circuits and deliver speeds of up to 12 fps (RAW + JPEG) and 14 fps (JPEG). Compared with the predecessor, Canon's DIGIC 4 Image Processor, the Dual DIGIC 5+ Image Processor offers approximately 17x faster processing speed, and feature new algorithms that promote greater noise reduction at higher ISOs. In addition to conventional image processing functions the Dual DIGIC 5+ Image Processors offer real-time compensation for Chromatic Aberration in both still and motion images. With the power of these two processors, speed improvements are noticeable from the instant the camera is turned on and the stunning results speak for themselves.

TUTORIAL E : Enjin Carian (Search Engine) dan Strategi Carian



Apa itu Enjin Carian?
Enjin carian ialah sebuah pangkalan data yang menyimpan pautan-pautan laman web dan kata kunci atau frasa. Apabila anda menaip kata kunci ‘Malaysia’ pada Google atau Yahoo! misalnya, enjin carian akan mencari kata kunci yang dimasukkan dengan kata kunci yang terdapat di dalam indeks pangkalan data. Apabila kata kunci ‘Malaysia’ dijumpai, maka laman web yang berkaitan dengan ‘Malaysia’ akan dipaparkan kepada anda.
Walau bagaimanapun, tidak semua enjin carian adalah sama. Sesetengah enjin carian akan mengindeks nama tajuk halaman sahaja, sesetengah enjin carian pula hanya akan mengindeks kandungan sahaja.
Umumnya, servis carian internet boleh dikategorikan kepada dua: direktori dan enjin pencari. Ramai yang keliru dengan kedua-dua terma ini, sehingga ada yang merujuk Yahoo! sebagai sebuah enjin pencari. Sebenarnya Yahoo! ialah sebuah direktori, bukan enjin pencari.
Kekeliruan ini berlaku mungkin disebabkan penggunaan butang ‘search’ yang disediakan kepada pengguna. Ini boleh disalah ertikan oleh pengguna yang akan mengganggap servis yang digunakan adalah sebuah enjin pencari.
Apa yang membezakan antara enjin pencari dengan direktori ialah, pangkalan data bagi direktori mengandungi senarai alamat web yang dimasukkan oleh manusia manakala pangkalan data bagi enjin pencari pula dikompil melalui perisian robot yang dipanggil ‘spiders’. Spiders digunakan untuk mengumpul maklumat yang terdapat di dalam sesebuah laman web.

Bagaimana Enjin Pencari Berfungsi?
Apabila program spider masuk ke dalam sesebuah laman web, ia akan melakukan satu proses yang dipanggil sebagai crawling atau spidering. Dalam proses ini spider akan mengumpul semua perkataan dan frasa yang terdapat di dalam laman web tersebut dimana perkataan-perkataan ini akan diindekskan ke dalam pangkalan data. Kaedah ini juga dikenali sebagai indexing. 
Apabila seseorang masuk ke dalam servis enjin carian dan memasukkan kata kunci tertentu, enjin pencari akan memadankan soalan carian pengguna dengan perkataan yang terdapat di dalam pangkalan data. Apabila pasangan yang sama atau hampir sama dijumpai, keputusan akan dipaparkan kepada pengguna. 

5 enjin pencari yang selalu digunakan:
1) Google.com
2) MSN.com
3) Altavista.com
4) MetaCrawler.com
5) Yahoo.com

Kebanyakan enjin gelintar dikendalikan oleh syarikat persendirian yang memiliki algorithme dan pangkalan data tersendiri. Antara yang cukup popular ialah Google dan diikuti oleh MSN Search dan Yahoo!. Antara enjin penggelintar versi tempatan pula adalah seperti Jejak Malaysia, Cari. Selain itu, beberapa percubaan untuk mewujudkan enjin penggelintar yang berasaskan sumber terbuka turut dilakukan, antaranya, Htdig, Nutch, Egothor dan OpenFTS.

STRATEGI CARIAN
Apabila kita berbincang berkenaan dengan carian yang cekap dalam menggunakan enjin carian di Internet, perkara ini merujuk kepada ketepatan maklumat yang diperolehi dalam masa secepat yang mungkin.
Enjin carian Google dibina dengan kaedah cariannya yang cekap dan pantas. Namun begitu, ada beberapa perkara yang memerlukan kecekapan pengguna enjin carian tersebut untuk mendapatkan carian maklumat yang tepat dan pantas. Perkara pokoknya adalah bagaimana untuk menyingkirkan terlebih dahulu laman-laman web yang tidak berkaitan dan keputusan carian yang tidak betul. Di sini akan dibincangkan beberapa faktor insan atau penggunaan carian yang betul bagi mendapatkan hasil carian yang lebih tepat dengan masa yang pantas apabila menggunakan enjin carian di Internet. Struktur binaan sesebuah enjin carian secara umumnya adalah sama di antara satu sama lain. Namun begitu, contoh yang akan diambil dalam perbincangan ini menggunakan enjin carian Google.

Berikut adalah beberapa kaedah yang betul untuk mendapat carian maklumat yang tepat dan pantas menggunakan enjin carian di Internet iaitu:-

1. Penggunaan kata kunci atau terma yang unik dan spesifik dalam suatu carian yang dibuat. Apabila sesuatu carian yang dibuat, enjin carian akan paparkan beratus ribu atau lebih alamat laman web. Jadi, untuk mengurangkan paparan tersebut, gunakan kata kunci atau terma yang sangat spesifik dan unik.

2. Penggunaan tanda tolak (-) dalam kata kunci pencarian. Fungsinya adalah untuk memperkecilkan lagi skop carian. Enjin carian akan menghasilkan keputusan carian yang di luar jangka terutama kata kunci yang digunakan mempunyai beberapa maksud. Tanda tolak ini akan berfungsi secara logik sebagai TIDAK atau penafian bagi sesuatu makna dalam kata kunci carian. Ia akan membuang beberapa keputusan carian yang tidak berkenaan. Sebagai contoh, sekiranya kita menggunakan kata carian berkenaan haiwan, kerbau. Maka segala yang berkaitan dengan kerbau akan dipaparkan seperti Kerbau Enterprise, nama bagi sebuah syarikat, kertas dan lain-lain. Jadi, boleh menggunakan tanda tolak untuk tidak merangkumi maklumat-maklumat yang tidak berkaitan tersebut seperti - Enterprise - Ker dan lain-lain.

3. Penggunaan tanda pengikat kata (" ") bagi mendapatkan kata kunci yang lebih bersifat spesifik dan merangkumi segala kata kunci tersebut. Ia tidak akan mencari maklumat secara umum yang berkaitan dengan kata kunci yang dicari. Ia adalah satu cara bagi mengurangkan paparan maklumat yang tidak betul, tidak berkaitan dan tidak tepat dalam sesuatu carian.

Contohnya adalah seperti kata kunci atau carian perkataan, "Membujur lalu melintang patah".

4. Pengunaan huruf besar dan huruf kecil. Kebanyakan enjin carian tidak membezakan sesuatu perkataan yang sama dengan huruf kecil, huruf besar dan yang berada dalam pengikat kata. Jadi, jangan membuang masa dengan perkara-perkara tersebut. Sebagai contoh, kesemua perkataan yang berikut adalah sama dalam enjin carian.

*Perpaduan
*perpaduan
*PERPADUAN

5. Tidak menggunakan perkataan kebiasaan dan tanda seruan. Ini kerana kebanyakan enjin carian akan abaikan perkataan kebiasaan yang digunakan dalam ayat untuk bahasa Inggeris seperti and, a, the, an, is dan lain-lain. Pengunaan tanda seruan juga akan diabaikan. Namun begitu, ia boleh digunakan dan enjin carian akan mengambil kira dalam proses carian sekiranya ia berada dalam pengikat kata (" ").

6. Penggunaan fungsi AutoComplete dalam enjin carian. Penyusunan terma kata carian daripada secara umum kepada yang lebih spesifik dalam kotak carian dapat banyak membantu memaparkan keputusan yang tepat dalam bentuk senaraian pada kotak carian tersebut. Inilah cara yang berkesan menggunakan fungsi AutoComplete dalam enjin carian. Pemilihan item yang bersesuaian pada kotak carian menjimatkan masa untuk menaip sesuatu terma carian. Fungsi AutoComplete ini bukan sahaja berada dalam enjin carian seperti Google tetapi ada pada pelayar web atau brwoser seperti Internet Explorer, Mozilla Firefox dan lain-lain.

7. Elakkan menggunakan kata carian berbahasa Inggeris yang mempunyai imbuhan perkataan seperti ballstestedwalking dan lain-lain. Lebih baik menggunakan perkataan asas seperti balltestwalk dan lain-lain. Ini dapat mengurangkan paparan maklumat yang tidak tepat dalam menggunakan enjin carian. Namun begitu, sekiranya carian maklumat memerlukan perkataan reading. Gunakan perkataan reading dalam carian maklumat kita.

8. Penggunaan Browser History atau fungsi sejarah dalam pelayar web seperti Internet Explorer, Mozilla Firefox dan lain-lain. Kadang kala ada alamat laman web yang sudah kita layari untuk dapatkan maklumat. Sekiranya ada keperluan lagi dan kita menggunakan enjin carian, seperti biasa ia akan paparkan banyak maklumat yang perlu kita perhalusi satu demi satu. Jadi, alamat laman web yang sudah kita layari sebelum ini boleh diperolehi semula di bahagian Browser History ini. Bagi memudahkan lagi carian kita, perlu kita mengingat masa dan tarikh laman web tersebut dilayari menggunakan pelayar web tersebut.

9. Hadkan masa carian dan tambahkan dengan pelbagai cara carian. Sekiranya dalam masa tertentu, masih belum menjumpai maklumat yang dicari, kita perlu ada kaedah atau perancangan yang lain seperti berikut:-
-Penggunaan enjin carian yang lain seperti Yahoo!, Lycos, Bing dan lain-lain.
-Membuat pertanyaan dengan menghantar soalan ke forum-forum elektronik yang berkaitan.
-Menggunakan pakar carian maklumat yang boleh membantu.
-Membuat panggilan telefon untuk sesuatu bantuan atau pertanyaan.
-Bertanya soalan atau maklumat tersebut kepada rakan taulan.

10. Perincikan carian maklumat yang dibuat. Terdapat beberapa simbol yang boleh diguna pakai dalam carian bagi menambahkan kespesifikan carian dan mengurangkan skop carian. Ia dapat mengurangkan paparan maklumat yang tidak sesuai. Di antaranya adalah seperti berikut:-

-Tanda tambah ( + ) - Enjin carian akan abaikan perkataan sambungan atau yang biasa digunakan dalam ayat seperti is, are, and dan sebagainya. Sekiranya perlu untuk kita masukan perkataan tersebut boleh menambah simbol tambah ini dipermulaan perkataan tersebut seperti giant +and city. Jadi, carian tersebut akan memaparkan segala maklumat berkenaan perkataan tersebut termasuk perkataan and.

-Tanda aliran ( ~ ) - Dengan penambahan tanda ini didepan sesuatu perkataan, enjin carian akan mencari maklumat perkataan tersebut dan maklumat yang sinonim dengan perkataan tersebut.
