No way in a right form to find cards mentioned in a Search — _self returns card_def rather than string, and we may want _self to return name or content, and in any case might want to be able to search for _self (use escaping for that?)
_name and _content don't work because...
very confused. what are you trying to do? there is no _name or _content. and _self should return a card in whatever view is specified outside of a search.
I think this all has to do with tracking card references in searches as a third kind of reference (like link or inclusion) which I believe is already ticketed. once we do that then WQL should handle the rest, no?
