All Implemented Interfaces:

Cloneable

public class NodeTermQuery
extends NodePrimitiveQuery

A NodePrimitiveQuery that matches nodes containing a term.

Provides an interface to iterate over the candidate documents and nodes containing the term. This may be combined with other terms with a NodeBooleanQuery.

Constructor and Description
NodeTermQuery(org.apache.lucene.index.Term t) Constructs a query for the term t.
NodeTermQuery(org.apache.lucene.index.Term t, int docFreq) Expert: constructs a TermQuery that will use the provided docFreq instead of looking up the docFreq against the searcher.
NodeTermQuery(org.apache.lucene.index.Term t, org.apache.lucene.index.TermContext states) Expert: constructs a TermQuery that will use the provided docFreq instead of looking up the docFreq against the searcher.

             int docFreq)

Expert: constructs a TermQuery that will use the provided docFreq instead of looking up the docFreq against the searcher.

NodeTermQuery

public NodeTermQuery(org.apache.lucene.index.Term t,
             org.apache.lucene.index.TermContext states)

Expert: constructs a TermQuery that will use the provided docFreq instead of looking up the docFreq against the searcher.

Method Detail

getTerm

public org.apache.lucene.index.Term getTerm()

Returns the term of this query.

createWeight

public org.apache.lucene.search.Weight createWeight(org.apache.lucene.search.IndexSearcher searcher)
                                             throws IOException

Overrides:

createWeight in class org.apache.lucene.search.Query

Throws:

IOException
