I've added a new endpoint to get searchable concepts rather than use all concepts in WoRMS. I haven't deployed it yet but it will be at https://fathomnet.org/api/boundingboxes/list/searchable and will be a drop in replacement for https://fathomnet.org/api/boundingboxes/list/concepts. It adds any terms from worms that will actually return hits in fathomnet when used in an all descendants search. I'll deploy it next week.
