That is a low tech html page that can search the SQLite database someone posted. That page is hosted on IPFS, which you can access through one of the gateways, although I posted a link to the page via one of the gateways.
On that page is a button you can press for more information on how to download it to your local computer to have a speedy local copy.
How I have been using it is: search in the following format: [name] [release year] [quality like 1080p] [encode like x265]
do note that the database is not being updated since RARBG is obviously gone now, but stuff prior and including some of 2023 is all there, most what rarbg released.
