gollark: Slower, even.
gollark: Oops, it turns out I'm accidentally sorting by it instead of the rank, but it's equally slow after fixing that.

gollark: It's not a condition, it's an extra row on the output, and I can see exactly what it does via `EXPLAIN ANALYZE`.
gollark: Maybe I need a better full text search backend?!
