    Description

      The recNum Stream Evaluator will return the index of the tuple in the stream. It is designed to be used with the select expression to append the index of the tuple to tuples in the stream.

      Syntax:

      having(select(search(testapp),
                    id,
                    recNum() as recNum),
             and(gt(recNum, 3), lt(recNum, 6)))

      Returns:

      { "result-set": { "docs": [ 
      { "recNum": 4, "id": "2e65eac8-7051-4a11-8409-b89e910bfedc" }, 
      { "recNum": 5, "id": "70edbf04-7dec-4e7f-86bb-71b97e737457" }, 
      { "EOF": true, "RESPONSE_TIME": 12 } ] } }
