Boolean operators provide a means for combining words and phrases by using special terms (AND, OR, NOT) to define, limit, or widen a search:
AND narrows a search. Use AND to combine search terms to reduce the size of the results list and to generate more specific search results.
Example: windows AND coverings
OR expands a search. Use OR to include synonyms or related terms in a search.
Example: shades OR blinds
NOT refines a search by excluding terms. Use NOT to exclude homographic terms (words spelled the same, but mean something different) or subcategories of topics that are not relevant.
Example: bulbs NOT incandescent
Example: bulbs NOT plant
