You can assemble an advanced query expression programmatically or simply pass a basic query expression to the search engine. The search engine provides many operators and modifiers for composing queries. Basic queries allow you to enter simple, comma-delimited strings and use wildcard characters. By default, a basic query searches for words, not strings. You can use wildcards, however to broaden the scope of the search.

Ordinarily, operators are employed in advanced query expressions. A basic 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. You can use the AND, OR, and NOT operators without angle brackets. This logic defines the qualifications a document must meet to be retrieved.
