Detailed Description
A Query that matches documents containing a subset of terms provided by a FilteredTermEnum enumeration.
MultiTermQuery is not designed to be used by itself.
The reason being that it is not intialized with a FilteredTermEnum enumeration. A FilteredTermEnum enumeration needs to be provided.
For example, WildcardQuery and FuzzyQuery extend MultiTermQuery to provide WildcardTermEnum and FuzzyTermEnum, respectively.
