Yep, it looks weird. The problem is probably that you have two attributes (MVA and
timestamp) with the same name.

Yes, that's what I was thinking. Now, I'm not really sure that it's what you actually
want, but the idea was to store all dates associated with a document in that attribute
and set a range filter on it. So if any of these dates is inside the filter's range the
document would match.
