Search Engines – Many people use internet to access information by knowing the website address known to you. And what about to those websites that are unknown from you? And if you don’t know that which website will provide you the information that you are required. In this case you need to take help of those search engines on internet which provide you to search information on the internet. So it is done through the search engines, a programme used for searching information on the internet. There are many search engines on the internet; I have given some examples below of some search engines.

Finding information using search engines

As I have mentioned above that there are many search engines on the internet. And I have also given many examples of search engines.  For searching information the process is similar in all the search engines.

Now we will start by choosing Google (www.google.com) as a searching engine which is one of the most popular search engines on internet.

3 Steps to search any information on the internet.

1. Go to the home page of the search engine (google.com)

2. Type the information in the box like structure that you will see on the page.

3. Now click on search button next or below to it. Now it will display you the list of links to the webpage, which are linked to your given information in just a few seconds.

Do you know How Search Engines Works?

The working of the search engines involve the following 3 elements that I have mentioned below.

Spiders or Webcrawler or Bots or Agents – The search engines use software called or known as Spiders or Webcrawler or Bots or Agents or Robot which combs the internet looking for the documents or the page and their web addresses. The Spiders or Webcrawler performs the methodical searches needed to find information which we have searched.

 The bots or spiders are given direction by the search engine and they crawl from one server to another, compiling the huge lists of URLs which are based upon the directions given by the search engines. So this is one of the main elements of a search engine.

Indexing software and database – The lists of documents and web addresses are collected by the bots and are sent to the indexing software. The indexing software extracts information from the documents and web addresses, prepares on the index of it and stores in a database.

The kind of the information that gets or indexed are based upon the particular search engine for example if you will go for searching “Amit Upadhyay” in Google Search engine then you will meet all the latest updated on internet about Amit Upadhyay but when you will search it in other search engines which is generated newly may show some other result from the result of the Google and otherwise it may also not show you any relevant result related to Amit Upadhyay. Some index every word in the document: or the other may index the document title only.

Search Algorithm – When you perform any kind of search by entering keywords’, the search engine software searches its database in which indexing software stores its entries using a particular search method called search algorithm. And then it displays the matching documents or web addresses.

This is all the working of a search engine or how a search engine works.
