Boolean operators

Search commands used by Internet search engines and commercial online legal databases to allow the researcher to combine keywords. The typical Boolean operators are AND, OR, and NOT. Some search engines also allow the NEAR command (such as "wiretap NEAR unauthorized") or proximity searches, typically using the "within" command placing the words "within" so many words of each other ("wiretap /3 unauthorized"). Check the "search tips" provided with most search engines to create more precise search strategies.
