org.apache.lucene.search.MultiTermQuery
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.
