Internet searching algorithm:
Searching: When a user enters a query into a search engine, the engine examines its index and provides a listing of best-matching web pages according to its ranking criteria. This short list, usually, have a short summary containing the title of the document and small part of the text. Most search engines support Boolean search. Some simple example of a search is given below: To find website which contains -java tutorial?, you may type Java tutorial in the search box of the browser. The search will look for keywords -Java? AND -Tutorial?;  the search expression will retrieve all those records where both the terms occur.
