First important thing to note - when you are searching in google.com you are not really searching www, But you are searching google indexed databases !
How these indexed databases are created ?
Here comes the Google Bots or Spiders, which crawl the entire www to retieve web pages with in webpages, web pages with in webpages ,web pages with in webpages........................and store words and its webpages in google database present across say 100 to several thousands machine.
These spiders were not so intelligent few years back.Because when sep 11 happened, google users were searching NewYork twin towers and google results were displaying nothing relevant to that sad event because their index was 1 month old !
But by now i guess these crawlers are smart enough to travel ever hour for the websites whose data changes often and every month for the websites whose data changes not so often.
If you create a new website,to display in google results either you have to submit the link to google or wait till crawlers retrieve your website pages

What happens when you enter some text say 'upendra', my favoutite actor :) in google text box and hit Search?
There might be billion pages in google indexed DB. Which of thses will be diplayed first ?
This is based on many factors like below
1. PageRank concept which was started by google founders Sergey Brin and Lawrence Page
Each website is given rank based on website authenticity , website quality, its references in other websites
2. Word frequency in the pages
3. Any synonyms of the words in the pages.
4. Word presence in page url, page title
It creates overall score of all above and displays the page with maximum score first.
We have already reached the stage where we are so much dependent on Google for even smallest of our daily tasks. As Google Fellow Amit Singhal says their aim is to answer questions like "what is the best time for me to sow seeds in some village in india, if there is early monsoon this time !! " in the very near future.
Google Search is becoming intelligent, making us dumb gradually !!
