How does a search engine work?
Hi,
Search engines work by crawling hundreds of billions of pages using their own web crawlers. These web crawlers are commonly referred to as search engine bots or spiders. A search engine navigates the web by downloading web pages and following links on these pages to discover new pages that have been made available.
Search engines work by taking a list of known URLs, which then go to the scheduler. The scheduler decides when to crawl each URL. Crawled pages then go to the parser where vital information is extracted and indexed. Parsed links go to the scheduler, which prioritizes their crawling and re-crawling.

A search engine is a software system that is designed to carry out web searches (Internet searches), which means to search the World Wide Web in a systematic way for particular information specified in a textual web search query.
A search engine is a web-based tool that enables users to locate information on the World Wide Web. Popular examples of search engines are Google, Yahoo!, and MSN Search. ... The information gathered by the spiders is used to create a searchable index of the Web.
Search Engine Results Pages (also known as “SERPs” or “SERP”) are Google’s response to a user’s search query. SERPs tend to include organic search results, paid Google Ads results, Featured Snippets, Knowledge Graphs and video results.
Search engines have three primary functions:
Crawl: Scour the Internet for content, looking over the code/content for each URL they find.
Index: Store and organize the content found during the crawling process. Once a page is in the index, it’s in the running to be displayed as a result to relevant queries.
Rank: Provide the pieces of content that will best answer a searcher's query, which means that results are ordered by most relevant to least relevant.
