Word stemming is applied to all individual terms in the search query, except within quoted phrases, or when the <WORD> operator is used. The stemming of query terms means that a query term will match documents containing morphological variants of that term. For example, a search for dogs AND go would match a document containing the terms dog and went. (This example applies to English; stemming employs language-specific information and depends on the user's locale and the language used to index the document.)
