    - #### ExitableTerms

          public ExitableTerms(Terms terms,
                               QueryTimeout queryTimeout)

      Constructor

  - ### Method Detail

    - #### 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:
        `intersect` in class `Terms`
      Throws:
        `IOException`

    - #### iterator

          public TermsEnum iterator()
                             throws IOException

      Description copied from class: `Terms`
      Returns an iterator that will step through all terms. This method will not return null.
      Overrides:
        `iterator` in class `FilterLeafReader.FilterTerms`
      Throws:
        `IOException`
