Understanding Concept Operators

You use Verity's concept operators to specify more than one search word or search element. The concept operator tells Verity whether you mean that all the search words or elements must be present in the document for it to count as a match, or if any one word or element makes the document count as a match. The concept operators include AND and OR.

The AND operator indicates that all the search words or elements must be present in a document to make it count as a match. Here are some examples:

 CRITERIA="sick AND days AND illness" CRITERIA="sick <AND> days <AND> illness" CRITERIA="AND (sick,days,illness)" 

The OR operator indicates that a document counts as a match if any of the search words or elements are present in it. Here are some examples:

 CRITERIA="sick OR days OR illness" CRITERIA="sick <OR> days <OR> illness" CRITERIA="OR (sick,days,illness)"
