What is Search Engine

Search engine is a web based tool or software, which helps internet users to search information on the World Wide Web. For example, Google, Bing, Yahoo, Baidu and Yandex are popular search engines. When the user types a word in the search bar, it is called a keyword. Based on these keywords and keywords, search engines display a long list of web results in front of the user.

The list of results that the search engine shows us in the form of website link, image and video, that page is called search engine result page (SERP). For example, before reaching this page of our website, you must have searched on Google search engine by writing “What is a search engine”. In this case, the word search engine is a keyword. By which search engines find out what users want to know about.

The rest of the sentence is called a key phrase, which helps to show the best match result to google or other search engine. So overall Search Engine is such a service, which we are able to access through Internet. It searches that information from the information database based on the user’s query and puts such results in front of us using its algorithm. In which we could get the exact results of our questions.

Top 5 search engines of India

Internet is an important part of our daily life in today’s time and search engine is the backbone of internet. You can access every information on the Internet through search engines. So let us now tell you about some popular search engines in India, which you might also be using.

There is no doubt that Google is the most used search engine in the world. There are about 63000 searches per second in Google. Just imagine, so many times per second search is done, then what will be the number of daily and whole year. If you look on the basis of this number, then there are about 2 trillion searches per year in Google. Google was started in 1997 by American computer scientists Larry Page and Sergey Brin.

Google has about 92.81% share of the search engine market share, the biggest reason for Google’s popularity is its information database, search anything you will get an immediate answer.

Bing

Bing is created by Microsoft. Microsoft CEO Steve Ballmer started it in the year 2009. Bing comes second in the list of popular search engines after Google. Microsoft replaced bing with its old search engines Live search and MSN search. Bing is often seen as a competitor to Google.

But in reality there is no comparison between these two. Bing is at number two with a share of about 2.38% of the search engine market share.

Yahoo

Yahoo is also a well-known name in the world’s largest search engine. Apart from being a search engine and portal, Yahoo also provides many other services. yahoo mail is the most famous of these. Compared with google, yahoo is not able to show as fast and accurate results and perhaps that is why it is not so much preferable as a search engine.

AOL.COM

AOL is an American web portal and online service provider company. Although the AOL search engine is not used much in India, but it is a great search engine according to Hindi search. Millions of Hindi websites and blogs are present in this, which provide you information in Hindi language. Its share is considered to be around 0.06 % in the search engine market.

Yandex

Yandex has got the status of Russia’s most popular search engine. Yandex is famous in Russia just as google is shadow in India. It was started by Arkady Valozh and Arkady Borkovsky in 1997. Apart from the search engine, it also provides many other services. Its market share in India is only 0.01%. Finding information on Yandex is as easy as on Google.

How search engine works

Let us understand what is a search engine? But the more interesting thing is, how do search engines work? Whenever you search by typing a keyword or key phrase in the search box. So how can it show us the exact result? This work is done by the search engine in three phases. In which Crawling is the first, Indexing is the second and Retrieval is the third phase. Let us understand a little better about these three.

What are the three primary functions of a search engine.

1) Search Engine Crawling

Crawling is a search process, in which a new or old website is scanned by the search engine. Robot (also called crawler and spider) is used to perform this task. These spiders find the content of a website through its link. Their job is to scan the website and collect details about every page of the website.

Spiders scan the title, url image, keywords of a web page and find out what the web page is about. If links to many other web pages are found in that page, then spiders reach the next page with the help of that link and start scanning it. Similarly, this automated bot keeps scanning millions of webpages through links. If some intellectuals are to be believed, then Google crawler can scan thousands of web pages in a second.

2) Search Engine Indexing

Once the crawler has scanned any web-page, after that the process of indexing starts. The crawled data is stored in the database. A sufficient number of servers are kept on this database center, which store all the copies of the web page being created by the crawler. This repository of web pages is called index.

This is the data that you see as a search result while searching for information in the search engine. It is the process of organizing a mass of data and web pages so that search engines can quickly find results relevant to your search query.

3) Search Engine Ranking and Retrieval

The third and final stage is Ranking. In this, the search engine processes the query we have searched and places such relevant pages in front of us, in which the correct answer to our question can be found. The web page that we see the most in the search result is the most relevant to your query according to the search engine. Now the question is, how does Google or any other search engine decide that the web page ranked in the first number is better than the second number.

Ranking Algorithm is used for this. Each search engine may have a different ranking method. All search engines keep their algorithms secret, so that no web creator can come up wrongly using those algorithms. But web builders try to bring their web page ahead of others by making better use of SEO (Search Engine Optimization).

Types of search engine

Search engine has become a great tool for us to find information today. To know about a topic, you do not need to find resources, just put the topic on the search engine, you will have all the websites that give information about it. There are different types of search engines to find the information you are looking for.

Search engines are classified into the following three categories.

Crawler Based Search Engines
Directories
Hybrid Search Engine

1 Crawler

All crawler based search engines use spiders, crawler, robot and bot programs to crawl and index new content in the database. Before showing any website in search results, it follows four steps, crawling, indexing, calculating relevancy and retrieving result. This type of search engine is most useful.

Crawler Based Search Engine Example:

Google
Bing
Yahoo

2 Directories

Web directory, which we also know as subject directory, is a type of directory system. In this, a list of websites is given on the basis of category and a short description of what the website is about is also given. The owner of the website himself submits his website to these directories. There is also a search box in these directories. On which by putting your query, you will get links to those websites which are giving information about this. This type of search engine is completely human operated.

Directory Based Search Engine Example:

Yahoo Directory
DMOZ
BOTW

3 Hybrids

It is a mixture of crawler and directory based search engines. Google or other crawler based search engines use crawlers as the primary system and directories as the second system. Search engines falling in this category can show you the details of the webpage from both the crawler and the directory in their results. This is a good option, where you can get human driven results and crawler results on the same search engine.

But nowadays human based directories are disappearing, due to which now hybrid search engines have become completely crawler based.

Hybrid Based Search Engine:

Yahoo
Google
