What do you understand by a search engine?

[Electrum]

Search engines work by crawling the web using bots called spiders. These web crawlers effectively follow links from page to page to find new content to add to the search index. When you use a search engine, relevant results are extracted from the index and ranked using an algorithm.

A search engine is a software system that is able to deliver relevant search results in response to a user's query. As well as delivering a list of relevant web pages, search engines can deliver other kinds of results such as inline results (instant answers), or video and knowledge graph results. A search engine system provides an interface that enables users to query for information in the index and receive results. A common way of approaching the process consists of four main steps: preprocessing, indexing, Search, and post processing.
