OK.  Clearly that shouldn't be happening, and we have tests in the test suite
to confirm that (t/511-sort-spec.t)... it seems they aren't rigorous
enough...

In the absence of a failing test case, I have some questions:

  * Is this index built all at once, or modified incrementally?
  * Are you using a SortSpec?
  * If you're sorting by score (the default), what are the scores of the hits?
  * Any deletions?
