gollark: It's an "xor filter", which is a new thing which is apparently mildly more space efficient than Bloom filters but slower to construct.
gollark: It's an inverted index thingoid. Each term has a compressed bitmap of document IDs. Each document lists the terms in it and their count, and has a probabilistic filter thing for nearness queries.
gollark: There are only a few MB of stuff in there (big documents, not lots of small ones).
gollark: I also haven't checked if it breaks horribly with more than 3 data.
gollark: The code quality of the entire thing is *not ideal*, and it has a few mildly apiaristic limitations, but whatever.
