PostgreSQL Full-Text Search for CJK Video Metadata

PostgreSQL Full-Text Search for CJK Video Metadata When I started thinking about migrating TopVideoHub to PostgreSQL, full-text search was the feature I was most curious about. Our video database spans Japanese, Korean, Traditional Chinese (Taiwan and Hong Kong), Vietnamese, and Thai — a real gauntlet for any search system. Here's what I learned implementing PostgreSQL FTS for a multi-script video platform. Why PostgreSQL FTS Over SQLite FTS5 SQLite FTS5 works, but PostgreSQL offers something more powerful: weighted tsvector columns with configurable text search configurations (TSC) per language. You can weight the title field more than the description, rank results by relevance, and even combine searches across multiple languages in a single query. The downside: CJK text (Chinese, Japanese, Korean) doesn't tokenize well in PostgreSQL's built-in configurations. We'll address that head-on. Setting Up the Schema First, create the videos table with a dedicated tsvector column: CREATE TABL
