  1. There was some work toward this, not sure about its current status: https://github.com/postgrespro/rum Badly needed.
  2. …who wrote core text search and json indexing. not sure why rum not in core. we have no problems. https://github.com/postgrespro/rum

  3. the pg extension called "rum" is very performant on millions of pdfs. https://github.com/postgrespro/rum
  4. …like faster ranking of results in full-text search, with GIN indices including positional information, like github.com/postgrespro/rum.

  5. …Better full-text scoring is one for me that's missing in that list, TF/IDF or BM25 please see: https://github.com/postgrespro/rum

  6. …over the core fts. rum is written by postgrespro, who also wrote core fts and json indexing in pg. https://github.com/postgrespro/rum rum handles +20mil pdf pages, interactively.

  7. …is no index that helps scoring results. You would have to install an extension like RUM index ( https://github.com/postgrespro/rum ) to improve this, which may or may not be an option (often not if you use managed databases). If you want a…

  8. …such as TF/IDF or BM25. PG seems to lag behind here and hasn't be a lot of movement in a while 1. https://github.com/postgrespro/rum

  9. Mandatory mention of the RUM extension ( https://github.com/postgrespro/rum ) if this caught your eye. Lots of tutorials and conference presentations out there showcasing the advantages in terms of ranking, timestamps...
  10. …results. The GIN indexes for FTS don't really work in conjunction with other indices, which is why https://github.com/postgrespro/rum exists. Luckily, it sounds like you can use your existing indices to filter and let postgres scan for…
  11. That why this really needs to get merged: https://github.com/postgrespro/rum
  12. …faster and better ranking (TF/IDF). Really would make PG a much more complete text search engine. https://github.com/postgrespro/rum
  13. …has been that sorting by relevance ranking is quite expensive. I looked into this a bit and found https://github.com/postgrespro/rum (and some earlier slide decks about it) that explains why the GIN index type can't support searching and…
  14. …[2] - slides https://www.pgcon.org/2019/schedule/attachments/541_Let's%20... [3] - https://github.com/postgrespro/rum

  15. I suggest to have a look at https://github.com/postgrespro/rum if you haven’t yet. It solves the issue of slow ranking in PostgreSQL FTS.
  16. …be introduced into the pg core soon. we index many terabytes of pdf files excellent performance. https://github.com/postgrespro/rum also, postgrespro are behind the json/b indexing.

  17. …Algolia but it could be a whole lot better for many use cases specifically TF/IDF and BM25 scoring: https://github.com/postgrespro/rum
  18. Would like to see this work integrated: https://github.com/postgrespro/rum
  19. PG could really do most of it if they got serious about https://github.com/postgrespro/rum with TF/IDF ranking.
  20. …allowing for a simple, elegant classification: find all queries which match a certain document. https://github.com/postgrespro/rum
    comment by johnthescott · 2019-11-01 · in Fine tuning full text search with PostgreSQL 12
  21. …we have the text search index easily handling 20mil+ pdfs with the rum index from postgrespro http://github.com/postgrespro/rum .
  22. …also BM25. There has been some work but not sure when it will be stable, needs a new kind of index: https://github.com/postgrespro/rum
  23. …is definitely A Problem I Would Love To Have ;) EDIT: This seems to help with the ranking problem: https://github.com/postgrespro/rum
  24. https://github.com/postgrespro/rum
  25. Still waiting for PostgreSQL to implement TF-IDF ranking: https://github.com/postgrespro/rum
    comment by SigmundA · 2019-04-10 · in TF-IDF in a Nutshell
  26. …indexes do not store enough information to use better scoring and RUM indexes could change that: https://github.com/postgrespro/rum
  27. …style rank generation ? The work on RUM seems to have stagnated (and TF-IDF was a todo anyhow here) https://github.com/postgrespro/rum I have a theory that if they incorporate these algorithms, it makes postgres potent enough that a lot of…
  28. …The downside: ranking can be slow when your keywords match a large number of documents (have a look at github.com/postgrespro/rum for a solution), and faceting is more difficult to implement than in ElasticSearch
  29. …row, and this can be really slow. People are working on this but it's not in PostgreSQL core yet: https://github.com/postgrespro/rum . This is why I'm a bit surprised by the numbers you shared: fulltext search on 270 million rows in below…
  30. …on the same topic which are interesting. You can see the RUM index (which has faster ranking here): https://github.com/postgrespro/rum
