what is search engine?

A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files. Some search engines also mine data available in databasesor open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

why search engine?


Searching through best sources like Google and Yahoo not only enhances the search results but it also enables users to cut down extra results. You can customize your search by using special marks and precisions. Advance searching is facilitated on different searching tools. You can also search about a particular word. Also you have an option to specify the type of information you are looking for. You can mention the type of file to cut down the search of other information.
Organized information:
Instead of exploring blogs and websites to find the relevant information, the results of search bars are organized. They will give relevant information which is organized and precise.
Best results of any search are possible if you know how to use these tools for searching. Learn techniques to improve your searching techniques.
