Overview


A query expression is any statement you enter as criteria for performing a search. The words and operators you use in a query expression comprise its elements.

When the simple query parser (the default parser) is used, you can state a query expression using simple or explicit syntax. The syntax you use determines whether the search words you enter will be stemmed, and whether the words that are found will contribute to relevance-ranked scoring.
