Changes (by olly):

  * milestone:  => 1.2.x


Old description:

> OP_ELITE_SET should never select groups of terms which don't match any
> documents.  (Currently, will exclude those for which termfreq_max() is 0,
> but this may still result in a bad choice)

New description:

 OP_ELITE_SET should never select groups of subqueries which don't match
 any
 documents.  (Currently, it will exclude those for which termfreq_max() is
 0,
 but this may still result in a bad choice).

Comment:

 No API or ABI changes required, so suitable for fixing in 1.2.x, so
 setting milestone to reflect this.  Probably not a high priority though.
