PostgreSQL Full Text Search scenarios with empty results on specific query configuration

postgresql full-text-search tsvector indexing SQL

I'm stuck trying to I'm deploying to production and I've been banging my head against this for hours. I'm currently working on implementing full-text search in PostgreSQL, but I've hit a snag where my queries return empty results even though I expect matches. I'm using PostgreSQL version 13.3. Here's a snippet of my setup: ```sql CREATE TABLE articles ( id SERIAL PRIMARY KEY, title TEXT, content TEXT, tsv_content TSVECTOR ); CREATE INDEX idx_gin_tsv_content ON articles USING GIN(tsv_content); UPDATE articles SET tsv_content = to_tsvector('english', coalesce(title, '') || ' ' || coalesce(content, '')); ``` After creating the index and populating the `tsv_content`, I ran a query to test it: ```sql SELECT * FROM articles WHERE tsv_content @@ to_tsquery('search & term'); ``` However, this returns no results, and I'm confused because I know that there are articles in the table that should match. I even tried using `plainto_tsquery`, but the result is the same. I verified the content by running: ```sql SELECT * FROM articles; ``` and there were indeed articles with titles and content that should match the query. I've also confirmed that my `tsv_content` is updated correctly by running: ```sql SELECT id, tsv_content FROM articles; ``` The `tsv_content` field shows the expected tokens. My next step was to try a simpler query with just one of the terms: ```sql SELECT * FROM articles WHERE tsv_content @@ to_tsquery('search'); ``` Still no results. I'm wondering if there's an scenario with how I'm indexing the text or if there's a question with the way I'm constructing the tsquery. Any advice on this would be greatly appreciated! I'm coming from a different tech stack and learning Sql. Any examples would be super helpful. My development environment is macOS. What would be the recommended way to handle this? The project is a mobile app built with Sql. Thanks for taking the time to read this!
