But mostly, I want to be able to query - get all ids for a thread since a timestamp, or all ids matching a domain, or filter out certain users or ids with less than 2 karma, filter out certain fields, etc. Firebase supports queries, and I wish the API did too.
I can accomplish this myself by just dumping everything into a DB, web scraping, using the Algolia API which does some of this but is rate limited, but I just wish the API did it.
