What is Search Engine and how does it work

How Search Engine Works

Search Engine works in three steps. First Crawling, Indexing, Ranking

Crawling is the first step to search any web page. In this, Spiders, Bots or Crawlers of any Search Engine go to all the websites submitted in the Search Engine and from there they collect the pages that match the keywords searched by the user. In Crawling, the Search Engine collects all the data it has, which contains the user’s keywords.

Indexing is a process where all the data found during Crawl is to position all the data in the database. Search Engine does not just Crawl a website, but Crawl and Indexing all those websites in the world. According to the Google Search conference, Google Spider Crawl 3 Trillion Pages per day. This means that Google has a library of all the information in the world.

Ranking and Retrieval
Ranking and Retrieval is the last but the most important step of any search engine because it is why it ranks a page after taking into account many reasons in which it not only looks at the web page but also see that it The website is so popular, how old it is and how good the content is.

Which gets the page ranked at the right place and then when you search for any information, you get not one but thousands of results. The information that Search Engine likes best is that the result appears at the top, then the second third, fourth and then at the bottom there are thousands of more results. Each Search Engine has its own different algorithm in Ranking and Retrieval.
