intersect

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

Description copied from class: Terms

Returns a TermsEnum that iterates over all terms that are accepted by the provided CompiledAutomaton. If the startTerm is provided then the returned enum will only accept 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.

NOTE: the returned TermsEnum cannot seek

Overrides:

intersect in class Terms

Throws:

IOException

iterator

public TermsEnum iterator(TermsEnum reuse)
                   throws IOException

Description copied from class: Terms

Returns an iterator that will step through all terms. This method will not return null. If you have a previous TermsEnum, for example from a different field, you can pass it for possible reuse if the implementation can do so.

Overrides:

iterator in class FilterLeafReader.FilterTerms

Throws:

IOException
