Method Details

intersect

public TermsEnum intersect(CompiledAutomaton compiled,
 BytesRef startTerm)
                    throws IOException

Description copied from class: Terms

Returns a TermsEnum that iterates over all terms and documents that are accepted by the provided CompiledAutomaton. If the startTerm is provided then the returned enum will only return terms > startTerm, but you still must call next() first to get to the first term. Note that the provided startTerm must be accepted by the automaton.

This is an expert low-level API and will only work for NORMAL compiled automata. To handle any compiled automata you should instead use CompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms) instead.

NOTE: the returned TermsEnum cannot seek.

Overrides:

Throws:

IOException

iterator

public TermsEnum iterator()
                   throws IOException

Description copied from class: Terms
