How does the search engine work ?

In earlier times there was no internet but after the invention of internet, many problems related to human life started to go away. At that time it was not used as much as it has been used since the invention of search engines.

As soon as the search engine was invented, after that more than half of the work of the people depended on the search engine. Let us know in detail how the search engine works

Mainly search engine works in 3 processes. Let's know in detail these three processes -

  • Crawling : - Crawling is a place where data of each website is collected. Crawling is the task of scanning a website linked to any of the questions we put in and collecting a complete description about each page to include a space. Apart from this, he shows the title picture keyword and other links related to our question on the page presented. If we already have a link, it helps us the most to reach that link. He also explains where you should now go beyond this and where you can get the right answers related to your question.

  • Indexing : - Indexing collects all the answers to the queries we search and creates a database in which all types of information are given in detail. Just as a library contains all types of books, indexing also works while crawling. Thousands of website drives can be assembled and displayed through indexing.

  • Retrieval and ranking: - With the help of retrieval and ranking, we can easily find anything through search engines. We can give the right answer to our questions only, who have all the answers to our questions, only then we can easily believe that thing. By entering just a small word on the search engine, you get the answer to the whole question. On the search engine, there is a lot of content, keywords and content pages and titles that help us find them easily. The second way is ranking with which we can easily get answers to questions related to any word or sentence on any page of Google.

In the early times, when the Internet was invented, people did not know of any proper source of obtaining important information. The invention of the search engine has given the entire universe a different and expanded form. In which they can easily get information about every thing in the universe about which they have heard only in stories. While search engines on one hand give information to people, on the other hand, search engine makers give people a chance to connect with a big engineer and at the same time search engines have become an easy way to get a good income.
