    Description

      Spinoff from this user thread: http://markmail.org/thread/vwdvjgupyz6heep5

      If you have a segment that has points, but a given field ("id") didn't index points, and a later segment where field "id" does index points, when try to merge those segments we hit this (incorrect!) exception:
