- SigmundA 5y agoThat why this really needs to get merged: https://github.com/postgrespro/rum https://github.com/postgrespro/rum
- rattray 5y agoTF/IDF is listed as a TODO on that repo, and I don't see a PR which promises to provide it.
- SigmundA 5y agoIt lays the groundwork by storing the needed metadata in the index, yes it needs more work and I wish there was more interest to do it. I really think the is a neglected area and if PG was able to merge in TF-IDF and BM25 there would be little reason to use a separate search db / engine and many advantages with it being integrated.
