---------------------------------------------------------------
[[email protected]], can you provide a quick summary of the issue. I see lot's
of symptoms in the ticket but I don't see the details of the inner workings of
the bug.
I'm concerned this bug may be hitting us in many different places besides
facets, such as field collapsing, and exporting.

> Our setup is based on multiple cores. In One core we have a multi-filed with
> integer values. and some other unimportant fields. We're using multi-faceting

> manufacturer: false AND id: (15039 16882 10850
