What Is Boolean Logic ?
| AND, OR, AND NOT & NEAR |
|
BOOLEAN LOGIC Way to combine terms using "operators" such as "AND," "OR," "AND NOT" and sometimes "NEAR." AND requires all terms appear in a record. OR retrieves records with either term. AND NOT excludes terms. Parentheses may be used to sequence operations and group words. Always enclose terms joined by OR with parentheses. Which search engines have this? See +REQUIRE or -REJECT TERM and FUZZY AND. Want a more extensive explanation of Boolean logic, with illustrations? |
