Purpose: Use Boolean operators to search with strategy
Boolean operators, or connectors, are used to retrieve relevant results. The Boolean operators are the conjunctions AND, OR, NOT. Boolean logic derives from mathematician, George Boole.
- Searching with AND connects words/phrases. The results must have both terms in the results.
- Searching with OR will contain results with either search word/phrase indicated but not necessarily both terms on either side of OR.
- Searching with NOT excludes a specific word/phrase. The results will contain the term appearing before the connector "NOT" but will exclude the term after the connector "NOT."
These concepts are represented with Venn diagrams in the tables below.
