In my fish course, http://www.memrise.com/course/750078/tropical-coral-reef-fish-identification/, I have an item whose name in the first column is “Potter’s angelfish”. When I’m editing the database and search for “angelfish” I get a list of most of the angelfish in the course, but I just noticed that Potter’s is missing. If I instead search for “potter” it does come up. But it should come up in the search results for “angelfish” along with all the rest, and it is omitted.
Edit: Actually, it seems to be inconsistent. I tested a few times when I posted, but now about 20 minutes later I notice that a search for “angelfish” does include Potter’s, but this time it omits “Queen angelfish, juvenile”.
