What is the search engine and how it works?


Do you know what the search engine is and how it works? Along with this, I am going to give you some more information. Today's time is the Internet and the Internet is nothing but information. Whenever there is a question in your mind, in this 21st Century, the Kaui people do not even ask people from nearby people or, to their teachers. They take their mobile directly and whoever has questions in their mind, they write it. They get answers within a few seconds.

Whenever a question arises between friends, the answer is, then the answer on the Internet also means search on a search engine like Google, Yahoo, Bing. But if we talked about 1990, then there was no such concept where you do some research and get it right away. At that time, there was no Internet.

Talk to thousands of people in the minds of people nowadays and everybody speaks on the Internet. This young generation tells it to Google This is the search engine that we will tell our readers today in this article. Let's start Google, Yahoo and Bing in this article, so let's start.

What is a search engine
Search Engine is a program. Or it can be said that this is a program that allows users to search for information or questions on the Internet (which is called Keyword / Phrase) from the unlimited database of the Internet, which can be accessed by the Information Search Engine (Google, Yahoo, Bing). ) Is found in the Search Result page. Just like Google does. Every question is searched on the world wide web.

Whatever search is done on the Internet, it is used to show the search engine Exact Result of Dhund. Some search engines have names like "Google, Yahoo, Bing". Let me explain you with an example. If you have a question in mind, then you immediately start searching Google which is a search engine. Just like your question is "what is computer and how it works".
Search engine Internet Search queries this question in any of the websites. Where these questions will match, the name of those websites will appear in the first page of the search result. You can then click on one of the links to read the answer to "What is a computer and how it works"

The question is what is called keyword in the language of the INTERNET. So now let's have a question in your mind that the search engine means Google, Yahoo, Bing, how it works. The information that you search also gives the correct answer. So let us know how.

How Search Engine Works


Already you have been told that whatever question, the text is written in your browser's search engine search, they are called keywords. If you type "what is a search engine" in google, then this keyword is. This keyword is found on the world wide web. When this keyword matches the content of the title or article of a website and matches it with the tag, it shows it in the search result. It was for the common man, think a little technically.

The search engine works in three steps. First 
  1. crawling,
  2. Indexing,
  3. Ranking & Retrieval
Know about these three in detail.

Crawling
Finding Crawling Meaning And better understand the acquisition of all the data of one of the websites or the complete information of a website. In this process, scan the website, what is the title of the page, keywords information, how many keywords are there in content, images and links are linked to in the page with the website. But nowadays, modern crawlers simply copy the entire cache of a webpage. Along with this, the page layout is like, Where is Advertise, where links are given, This is also a Store.
How does the search engine crawl the website? There is a self-propelled Bot that searches every new and old page called Discovery. Bots also speak spiders, who visit cores pages every day. But do not read like us or you like fast too quickly.

According to Google, nearly 100 to 1000 pages visit in 1 second. When bots get a new page, they send it back to end processing (page title, meta tag, keywords, backlink, images, videos). And then checks out which pages are linked and linked to this page.

Whenever a new page is found, then the process repeats itself. Crawling + backend processing + indexing This happens after page indexing without it Google can never see the correct search result at any time. But there are some websites that you can search through TOR NETWORK.

Indexing
Do not put too much emphasis on your mind It is easy to understand indexing. Indexing is a process where all the data that is available during the Crawl is to be placed in the database. Take a look You have a lot of books. You are Crawling to read every name of books, author name, books name, books, but listing all these details is only indexing. Now let's talk about this search engine does not just crawl a website, but crawl and indexing all the websites in the world.

According to Google Search Summary, Google spiders crawl every trillion pages every day. This means that Google has a library of all information in the world.
Google Search Engine is a big server of data. Where the data is stored in thousands of thousands of pages.

Ranking and Retrieval


This is the last step of the search engine, but this last step is just too complex. Because when you search in some google, the first thing to do is search the information of which you are searching the exact same information you get. The people of the search engine are trusted only when they show the user-related content removal. For this Google uses some algorithm. Those algorithms work according to some parameters. Some of which are content age, content keyword, content page title

There are 200 factors of Google for page ranking. It is through which it is ascertained that on searching the page should look at the search result of GOOGLE HOME. The rank algorithm is a big problem. Because of one billion web pages, who search google and show in the first page. However, all Hackers are putting their mind into hacking Ranking factors.

The first ranking is to guess how often keyword has been used in the post and how many backlinks it was. For some years now it has become very difficult to find google ranking factors. Every year Google is changing its algorithm. Because Google offers the sites to come first, which are really promoting. In this way, the search engine works in these three steps.

History of Search Engine
All the search engine work was the same. Searching and displaying internet pay data In the early days, Search Engine was a collection of nothing else, not just a File Transfer Protocol. The data that was connected to each other was connected to another server. Then there was only one way to connect with the world wide web internet. The search engine was created because it was not so easy to locate the web server and file.

But there were two Ph.D. students who had the name of Sergey Brin and Larry Page, who were students of Stanford University, California, in 1995, they met each other in 1995 and that same started the search engine.
Sergey Brin and Larry Page in 1996, when they were studying Ph.D., they tried to differentiate their Ph.D.'s research project and thought, "If we rank the website, compare it with another website, it would be great, This was the way to rank them in time, as often as the word searched, in that webpage, it will rank accordingly, and this idea is the form of Google today. Initially, they gave it the name BACKRUB. In 1997, both of the search engines were named "Google".

My final opinion on this article
Well, my opinion is that the best search engine is Google. Just like all the latest technologies like google search, voice search, speech, google assistant, technology is the Google technology. With this Google's search algorithm is increasing every year. The information about what the search engine is and how it works may have been completed.
