Search Engines: How they work?

How do search engines work?

A search engine is a word-search machine and is a primary method of finding web pages. When you type a word, phrase or sentence in a search engine, it immediately gives the results. It is better to use one word or a phrase rather than a sentence, which would not be so effective if a particular phrase does not give the desired results. The rephrasing of the phrase can give better results. The more specific you are, the better are the results.

A metasearch engine displays results from multiple search engines. In other words we can say that search engines harvest information. Search engines performance depends on how fast they perform a particular search. Some like the yahoo search engine perform a wider range of search than others. The search varies depending on the speed and performance of the engine. Information consists of images, web pages and other types of files. A search engine operates in the following manner- First comes web crawling, than indexing and than searching. Web crawler is also given the name ‘spider’ by techies. A vast majority of search engines are owned by private companies. Tons of information can be found by the help of these search engines.

The search engines can be used to find positive piece of information as well as negative pieces of information can also be found out. It depends on how you utilize these engines and the utilization varies from person to person.
