Anyone experienced with postgres full text search? I want to get something simple setup but couldn't get it to work. I want to match substrings like "/r/chatgpt" (sub reddits) in url links, but couldn't get it to match. Tried a few types of queries like phrase, plain, default, simple, english. All have some weird issues, either not matching special characters, or not matching substrings (partial match). Also I'm somewhat limited on the syntax side by what can be done with drizzle ORM.
