What is a search engine? How does a search engine work?


Who is not familiar with the word search engine now! There was a time when we knew something from different people around us. But in today's digital age we don't ask anyone if we know anything. Search the search engine directly on the mobile and get the answer. Not just questions but anything can be answered by searching the internet.



So its role in finding something is immense. In most cases we do not choose Google as a search engine. Because it is the largest search engine. There are also many more Search Engines. But many do not know what is Search Engine? Let's not know about it then.


What is a search engine?


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 marketing? How do I do marketing? To find out, you do a Google search. As soon as you search, the websites that have the answer to your question will show up on its search results page.


Then you can go to any website from the search results page and find out your answer. The query you searched for is called a keyword on the Internet.


And search engines have some algorithms through which he can understand which information is best for a keyword.


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.)


  • Secondary search engine (MSN, Snap, Hotbot etc.)


  • Targeted search engine (AOL search, likes, AltaVista, etc.)


However, there are basically 4 types of search engines. E.g.


  • Crawler Search Engine

  • Web Directories

  • Hybrid Search Engine

  • Meta Search Engine


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.
