      • 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 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

        .

                           throws java.io.IOException
        Description copied from class: Terms
        Returns an iterator that will step through all terms. This method will not return null.

                  throws java.io.IOException
        Description copied from class: Terms
        Returns the number of terms for this field, or -1 if this measure isn't stored by the codec. Note that, just like other term measures, this measure does not take deleted documents into account.

        Description copied from class: Terms
        Returns the sum of TermsEnum.totalTermFreq() for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.

      • hasFreqs

        public boolean hasFreqs()
        Description copied from class: Terms

                        throws java.io.IOException
        Description copied from class: Terms
        Returns the smallest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.
