A search engine is a software program that collects information and provides it when needed. You can compare it to a spider. Which spreads like a net all over the net world to collect its own information.

When you search for any information on the Internet, the search engine selects your information from the billions of webpages you have stored. Suppose, in your mind, the real,

What is the function of search engine?

Its job is to find the correct answers and information of words, sentences, questions etc. by the user. Displaying a list of different websites as information found in your Search Engine results page. This is the job of search engines.

Types of search engines?

Search engines can be divided into 3 categories based on their methods and algorithms. E.g.

• Primary search engine (Google, Bing, Yahoo etc.)

How does the engine work?

When we search in search engines for information, the searched keyword will match the title, description, content, etc. of a website, then those websites are shown on the search engine results page. Websites are shown on the search engine results page if the content of the website matches with the search keyword.

Moreover, the web search engine collects as much information as possible from all live websites by sending a spider or web scalar.

If it is not posted on a website for a long time or the old information is not updated, then the search engine does not stop visiting there, it visits regularly. In this way, the search engine bots collect all the information on the website by visiting millions of websites every minute.

Another helpful search engine program is Indexer. Its job is to read the information and store it in layers. Indexer deletes information from the Search Engine if any text is duplicated or not standardized or has a broken URL.

Moreover there is another program to delete data. That is the property algorithm. It deletes duplicate information and separates the required information. After searching the search engine, we get the correct and appropriate answer.
