Other Sorts of Search Tools

Some search tools, called search engines, work best by entering words or phrases within quotation marks. The database in search engines is compiled automatically by software “robots.” Other search tools, called directories, work best by “drilling” down through their selection of web sites. Directories are compiled by human beings who filter out the useless sites.

URLs for several popular search tools:

google.com
