Search engines are the best tools to use when you are looking for very specific information or when your research topic has many facets. Usually when you need information on a very detailed or multifaceted subject, a search engine will give you not only more information, but also the most precise and up-to- date information possible. Even though most of the major search engine databases attempt to index the entire Web, each one has a different way of determining which pages are most relevant to your search request. In one database, a relevant document may be fiftieth on the list; in another database, that document may be first. In order to retrieve the most relevant documents, you should become familiar with many search engines and their features.
