intersect
public TermsEnum intersect(CompiledAutomaton compiled, BytesRef startTerm) throws java.io.IOException
Description copied from class:Terms
Returns a TermsEnum that iterates over all terms and documents that are accepted by the providedCompiledAutomaton
. If thestartTerm
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 providedstartTerm
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 useCompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms)
instead.NOTE: the returned TermsEnum cannot seek
