Concept operators
Concept operators combine the meaning of search elements to identify a concept in
a document. Documents retrieved using concept operators are ranked by relevance.
The following table describes each concept operator:
Operator Description
AND Selects documents that contain all the search elements you specify.
OR Selects documents that show evidence of at least one of the search
elements you specify.
ACCRUE Selects documents that include at least one of the search elements
you specify. Documents are ranked based on the number of search
elements found.
ALL Selects documents that contain all of the search elements you specify.
A score of 1.00 is assigned to each retrieved document. ALL and AND
retrieve the same results, but queries using ALL are always assigned a
score of 1.00.
ANY Selects documents that contain at least one of the search elements
you specify. A score of 1.00 is assigned to each retrieved document.
ANY and OR retrieve the same results, but queries using ANY are
always assigned a score of 1.00.
