SEARCH ENGINES






So today we will be talking about SEARCH ENGINES. You know what does that means? let me introduce to you all about it since i just learnt about it. So we will be learning about it together. OKAY? 

A SEARCH ENGINES IS A WEB TOOL WHERE YOU CAN FIND ANYTHING BY ENTERING THE KEYWORDS AND FIND INFORMATION ON WEBSITESCONTAINED ITS DATABASE. 

The example of Search Engines are : GOOGLE and YAHOO. and both of them have their own database. 

user interface where user can put the query or type anything about the things that you are trying to find.  and after that result are presented according to relevance of subjects. 

But there are specific engine(Google Scholar, Art Cyclopedia)  that were created for specific purpose example like education purpose. We can find article, journal and essay there. 
and we also have meta search engine and it matches the user's query to multiple search engines. 

BUT THE THINGS THAT I AMAZED THE MOST IS THE  DEEP WEB. 
YOU CAN FIND THE THINGS THAT YOU COULD FIND IN THE NORMAL SEARCH ENGINES, IT CONTAINS 90% OF THE INTERNET but not accessible surface web crawlers. 
it is accessible only through certain browser.
