Collection filter facetValueId AND/OR selection

[michaelbromley]

Is your feature request related to a problem? Please describe.
I have a bunch of products with facetValue "book" or "dvd". I want to create a Collection "Books & DVDs" containing all variants tagged EITHER "book" OR "dvd". Right now if I select these 2 facetValues, a logical AND operation is performed and the result is zero results in the Collection (and resultingly in any child).

Describe the solution you'd like
There should be another parameter to the filter which allows the selection of AND or OR logical operator to decide how to interpret multiple facetValueIds.
