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.
The search query is everything that the user types to get results which is made up of one or more search terms, plus optional special characters.
●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.
