For example, Karno has a ton of pools. Alternatively, is there a way to search pools by description? Most people put the artist name in the title or description.
https://e621.net/pools?search%5Bname_matches%5D=karno Does not list all the pools.
I think I can parse the JSON to sort posts by pools and leave only unique pool numbers.

The ability to search by description is very much possible, and is located right under the name option
