Furthermore, the meaning of the search engines is a tool designed to search for the information on the World Wide Web. The result of the searched questions have generally presented a list and are commonly called it’s as hits. The searched information is consist of web pages, images, information, pdf and other types of files. Out of a lot of search engines, some search engines mine data available in databases, open directories or news books. There are maintained by human editors, search engines operate algorithmically or a mixture of algorithmic and human input. We can identify the search engines as the key to find specific information on the huge expanse of the World Wide Web. It would be virtually impossible to locate anything on the Web without knowing a particular URL and modern search engines.

Types of Search Engines


There are fundamentally two types of search engines. First one is powered by robots.it also called crawlers, ants or spiders based search engines. And the second one is powered by human submissions. As well as we can be found another type of search engines as a hybrid of the above two types.

Crawler-based Search Engines (crawlers, ants or spiders) 


Those that use automated software agents that visit a Web site or page, read the information on the real site and follow the links that the site connect to performing indexing on all linked Web sites. The crawler search engines return all the information back to a central depository, where the data is indexed. The crawler will from time to time return to the sites to check for any information that has changed. The frequency with that this happens is explained by the administrators of the search engine.

Human-powered Search Engines 


Those are powered by humans to submit the information that is subsequently indexed and cataloged. Only information that is submitted and put into the index. In both cases, when the query a search engine to locate information, their actually searching through the index that the search engine has created. And do not actually search the Web. These indices are huge databases of information that is collected and stored and searched.

Sometimes most of the user's search links on a commercial search engine, such as Yahoo or Google, will return results. Since the search results are based on the index, if the index hasn't been updated, a Web page became invalid. Then usurers are attracted to the use of famous search engines.
