Thanks - I should have included a few more details in my original question.
The issue is that I've got an index with 200M records, of which about 50M have
a unique value for this prefix (which is 32 characters long)
So adding another indexed field would be significant, which is why I was hoping
there was a way to do it via grouping/collapsing at query time.
Or is that just not possible?
Thanks,
