It can be defined as an internet-based tool that searches an index of documents for a particular term, phrase or text specified by the user which commonly used to refer to large web-based search engines that search through billions of pages on the internet. These search engines are based on particular mathematical algorithms. Search engine has a large database in which the index of web pages has been saved. Search engine uses a particular automated program to keep itself informed with the content of website this program is called crawler, robot or spider. It searches the most relevant document regarding the query or phrase and display the results in particular order.

Working of a search engine

Spider “crawls” the web to find new documents (web pages, other documents) typically by following hyperlinks from websites already in the database. Search engine indexes the content (text, code) in these documents by adding it to their huge databases and periodically updates this content. Search engine searches its own database when user enters in a search to find related documents (not searching web pages in real-time). Search engine ranks resulting documents using an algorithm (mathematical formula) that assigns various weights to various ranking factors.
