When Page showed up at Stanford a few months later, he selected human-computer interaction pioneer Terry Winograd as his adviser. Soon thereafter he began found himself attracted to the burgeoning World Wide Web as a doctoral thesis. Page found the Web interesting primarily for its mathematical characteristics. The World Wide Web, Page theorised, may have been the largest graph ever created, and it was growing at a breakneck pace.

Citations and Back Rubs

It proved a productive course of study. Page noticed that when you looked at a Web page, you had no idea what pages were linking back to it. He thought it would be very useful to know who was linking to whom.

It was Tim Berners-Lee’s desire to improve this system that led him to create the World Wide Web. And it was Larry Page and Sergey Brin’s attempts to reverse engineer Berners-Lee’s World Wide Web that led to Google. Which brings us back to the original research Page did on such backlinks, a project he came to call BackRub? He reasoned that the entire Web was loosely based on the premise of a link. If he could divine a method to count and qualify each backlink on the Web, as Page puts it “the Web would become a more valuable place.”

At the time Page conceived of BackRub, the Web comprised an estimated 10 million documents, with an untold number of links between them. Unaware of exactly what he was getting into, Page began building out his crawler.

The idea’s complexity and scale lured Brin to the job.

A Company Emerges

As Brin and Page continued experimenting, BackRub and its Google implementation were generating buzz, both on the Stanford campus and within the cloistered world of academic Web research.

Brin remembers speaking with his adviser, who told him, “Look, if this Google thing pans out, then great. If not, you can return to graduate school and finish your thesis.” He decided to just give it a try. Needless to say, the ‘Google thing’ panned out and is today the most popular search engine on the Worldwide Web.

Google search basics: Basic search help

Search is simple, just type whatever comes to mind in the search box, hit Enter or click on the Google Search button, and Google will search the web for pages that are relevant to your query.

Some basic facts

· Words like ‘the,’ ‘a,’ and ‘for,’ are usually ignored. But there are even exceptions to this exception. The search "the who"
likely refers to the band;

the query "who" probably refers to the World Health Organization — Google will not ignore the word ‘the’ in the first query.

Adding + before a word disables synonyms.

Search is always case insensitive.

Searching for 'North East' is the same as searching for 'northeast'

With some exceptions, punctuation is ignored.

Punctuation that is not ignored

· Punctuation that have particular meanings, like [ C++ ] or [ C# ] (names of programming languages), are not ignored.

· The dollar sign ($) is used to indicate prices

nikon 400 and nikon $400 will give different results.

· The hyphen - is sometimes used to strengthen connection between two words.

It is also a notable fact that Google changes its look on every special day. For example, let us say for Christmas, the main page of google looks like.....
