Advanced Search combining "AND" and "OR" for tags

Hi,
I’ve been reading today about the Tags structure of Discourse. I discovered it is possible to search for topics that are intersects (“AND”) or unions (“OR”) of tags. My question is:
is it possible to combine these in Advanced Search? E.g. would I be able to, using Discourse, to do a search for:
tag1 AND (tag2 OR tag3)
?
thanks
Rik

No that is not possible.
