How Search Engines Work ?
What happens when a searcher[users] enters keywords?
A Search engine does not examine every page on the web. When a user puts in a query on the search box, the engine first builds an index of it
– Custom database of all the words on all pages
– Search engine also stores other information.
☛ Firstly
●It examine the Query what the user are for searching, and then expand that query. Means check the words variants[ plural/singular, verbs, Nouns]
●Then check the Spelling on the Query.
● Check the word order
● Checks the search operator [e.g. putting IP: ip address] for searching the Ip of sites.
☛ Next It match the query presents on its database [SERVER]. After then It match the query with all the data that have been Crawled by it.
☛ The Results are sent to the Index Server where it is indexed that which query should be displayed first on the searched results.
● This results is made by the rank of the page, which is known as PAGE RANK.
