Not sure this is completely relevant here, but not sure where it should
go either.

I'm using Facet API to index a book catalog.
I have facets for authors, publishers, etc.

So far, when I apply several filters consecutively, each filter is applied only to those items that have already been filtered, not to the whole catalogue.

So for instance if I filter by author foo and then by publisher bar,
I'll see only those books written by foo and published by bar.

In some situations this behaviour is fine, but in other situations I would prefer that the filtering is done on the whole collection rather than on the already filtered results. So if I first ilter by author foo and then by publisher bar, I would like to obtain all the books published by bar, no matter whether they have been written by foo or not.

Is there a way to achieve this, please?

Thanks a lot for any hint.
