You can assemble an explicit query expression programmatically or simply pass a simple query expression to the search engine directly from an HTML input form. The Verity query language provides many operators and modifiers for composing queries. Simple queries allow end users to enter simple, comma-delimited strings and use wildcard characters. By default, a simple query searches for words, not strings. You can use wildcards, however to broaden the scope of the search.

Ordinarily, operators are employed in explicit query expressions. A simple query employs the STEM operator and the MANY modifier. The MANY modifier forces the documents returned in the search to be presented in a list based on a relevancy score. Explicit queries can be constructed using a variety of operators, including evidence, proximity, relational, concept, and score operators. You can use the AND, OR, and NOT operators without angle brackets.
