Custom Boolean Search

The information below describes how to create a search query in the Custom Boolean field.

Searching for a Word

NOTE: The search engine understands the language construct of the entered text and returns results with the terms highlighted accordingly. The results returned are based on the meaning and context of the search terms, rather than results that only match the text.

 

Searching for a Phrase

Searching for a Query

NOTE:  The search engine ignores the case of the search terms entered. For example, TEXAS, texas, and Texas return the same results.

 

Search Operators

A search operator is a Boolean connector to be applied to the search terms.  

Available operators:

AND

NEAR

NEAR#

NOT

OR

WILDCARD

 

Concept Operator

Selects documents that contain all the search terms.

Example: speaker AND appoint AND member

Result: Displays documents that contain speaker, appoint, and member as well as any related terms.
