[TYPO3-mvc] Multiple filter with mm relation

[Claus Fassing]

Hello,

I try to define more than one filter (category select) with mm relation.
e.g.
One item belong to more than one category. A set of select elements from 
frontend view should reduce the result.

 From sql point of view it could work with subselect, but how looks the 
query setup from extbase ?
Is this possible at all ?

Regards Claus
