If there were an easy way to find "and they were roommates!" we'd deal with filtering for ships. Apparently, this is not a tag that's used in general. (Also: Daughter is in her early 20's; she's not traumatized by ships; she just doesn't like most of them.) And yeah, AU-Neighobors/Roommates doesn't quite catch the "ahhahah they're stuck together!" that's most of what she's looking for. (She really, really wants Red vs Blue training academy fics, AU or not.) But mostly, even a lot of the neighborhood/shared room etc. fics aren't tagged that way.
...The biggest difference between AO3's tagging, and what inspired it (Delicious collapsing), is that Delicious was tagged by readers, not authors. And they were tagged by multiple readers with different focuses - the same fic might be tagged for relationships and kink in one place, and tagged for AU setting somewhere else, and specific sex acts in a third listing. Authors often don't notice all the details someone might be looking for, or they just don't want to spend twenty minutes writing two dozen tags for a 2,000-word fic.
I think I want to nudge AO3 into making their bookmark searching more robust. As far as I can tell, you can't even sort them by fandom.
