How Search Engines Works ?

Step 1 - Search Engines make use of software's called SPIDERS, which comb the internet looking for documents and their web addresses.

Step 2- The documents and addresses are collected and sent to the search engine's indexing software.

Step 3- The indexing software extracts information from the documents, storing it in a database.

Step 4- When you perform a search by entering keywords, the database is searched for documents that match.

Step 5- The search engine assembles a web page that lists the results as hypertext links.
