- booleansearch for term
A system used frequently in search engines and directories for searching and retrieving information using and combining terms such as AND, OR, and NOT for the purpose of sorting data."Boolean logic" is used to restrict an informational or statistical search to certain parameters. Boolean characters can be helpful when searching the Internet. For example, searching for "healthcare agency" produces more than 4 million matches, or all entries that contain either "healthcare" or "agency." But a search for "healthcare & agency" locates only the matches that contain both words, significantly limiting the results.
