I wanted to do a search for engines that have shadow support, but I couldn't find a way to do this. If I mark all shadow options, then the search is for an engine that supports all of them. I'd like a way to search for "either of these options". The same applies to some other fields. For example in the status search, it makes no sense to search for "beta and production", but it makes a lot of sense to search for "beta or production".
