Not Sure if this can work when the content view does not allow It. I guess you have to look into the source code...
Not sure if this helps, but I've tried building a number of different queries with the hopes of being able to use an "OR" operator for tags but was unsuccessful. We were trying to achieve something similar to how the 'watch a tag' widget works, but with a superlist tile. We cut a case to have Jive look (440085) and it boiled down to an 'idea' needing to be submitted as the /content page only uses multiple tags as an AND (vs. OR) operator, regardless of manually tweaking the syntax.
Thanks Bryce yeah that's my experience too. I've got it down to a list for content type and sorting but not tags - it's either content type or tags as far as I can see.
