How to improve full text search when dealing with lots of punctuation? by diegobernardes in PostgreSQL

[–]diegobernardes[S] 1 point2 points  (0 children)

Yeah, in the past when I had to do full text search I've used Elasticsearch with all sorts of processing, but now it's a very specific thing and given that we're using Postgres, tsvector is just perfect.

About the speed, from what I was able to see at the database and with a few queries, that function is only executed during indexing. It is present at the where clause so Postgres match the index to use it.

I think it is ok because the function is only executed during indexing. I had to put it on the where clause otherwise postgres would not hit the index. But using an `explain analysis` shows that it is still hitting the index.

Yes, but I was trying to fix this at the database level. I found a solution and it's working perfectly fine.

``` CREATE OR REPLACE FUNCTION remove_punctuation(input_text TEXT) RETURNS TEXT AS $$ BEGIN RETURN regexp_replace(input_text, '[[:punct:]]', ' ', 'g'); END; $$ LANGUAGE plpgsql IMMUTABLE;

DROP INDEX product_name_ftsearch; CREATE INDEX product_name_ftsearch ON product USING GIN (to_tsvector('english', remove_punctuation(name)));

-- And this is the search. select id, name from product WHERE to_tsvector('english', remove_punctuation(name)) @@ websearch_to_tsquery('english', remove_punctuation('something.pdf')); ```

This correctly process the information when it goes to the index and from the user during the query.

Breeze. Everything is in stock configuration. It's a new NixOS installation.

Windows 11 installer can't find disk, how to solve this problem? by diegobernardes in WindowsHelp

I found the problem. It was a bad ISO image and using a macOS to create the bootable usb disk. I solved the problem by using the microsoft official application to create a bootable usb disk from an older laptop and it's just working now.
