Search Engines Search engines look for key words in the title and content of web documents. It then displays links to the pages it finds that match your search request. Once the links are found you can click on each of them to find which one best fits your needs.
Some engines provide abstracts or summaries with their links.
This allows you to verify whether or not it is worth clicking on them. With search engines, you can usually use advanced searching techniques, such as searching for multiple terms. Meta Crawler is actually a search engine that searches other search engines in priority order. Meta Crawler decides which search engines are most likely to contain the information you are looking for and selects several at a time to search. Each search engine has a language of its own, a way to state a question so as to exclude obviously senseless answers.
