What Are Three Boolean Operators?
Three Boolean operators are the search query operators “and,” “or” and “not.” Each Boolean operator defines the relationships of words or group of words with each other. Another Boolean operator is the symbol “(),” which sets the order of considered relationships when multiple Boolean phrases are combined.
The Boolean operator “and” is used in a search query to pull all the records that contain all the words in the search category. The operator “or,” on the other hand, is used to retrieve records on any words that are being separated by it. In a search query, the operator “or” can also be replaced with the symbol “|” for the same effect. “Not” is used to narrow search queries and retrieve records that do not contain words or terms that follow its usage.
