Keyword Search Operators 

Keyword search supports the set of operators shown in table Keyword Search Operators. Each operator has some advantages and disadvantages.

Specifically: (1) progressive search has a compound effect when stemming is installed, finding variants of the search word in addition to the search word itself; (2) contains search finds substrings but is relatively slow; and (3) sounds like search is more forgiving about spelling errors but often returns many extraneous results.

Sometimes, however, you may want to apply a different operator to each of the words you specify for the keyword search. For example, you may want to perform a contains search on one word, an equals search on another word, a stemmed search on another word, and finally, a sounds like search on another word.

To achieve this type of hybrid search, the progressive search operator now allows you to tag each word with a wildcard for special handling.

The wildcards supported by the progressive search operator and their meaning are summarized in the table below.

Wildcards Supported by the Progressive Search Operator

Wildcard	Position	Syntax	Search Behavior
n/a	n/a	word	Stem then equal (default)
*	Prefix	*word [or *word*]	Contains only
*	Postfix	word*	Starts with only
=	Prefix	=word	Equal only
+	Prefix	+word	Stem then equal then sounds like

Be sure to put space between each of the search words.
