A phrase search is a search query that contains one or more multi-word phrases enclosed in quotation marks. The words inside phrase-query terms are interpreted strictly literally and are not subject to stemming or thesaurus processing. For example, if you define a thesaurus equivalence between Jennifer Lopez and JLo, normal (unquoted) searches for Jennifer Lopez will also return results for JLo, but a quoted phrase search for "Jennifer Lopez" will not return the additional JLo results.
