## AI overview

This comparison examines PostgreSQL native full-text search, ElasticSearch, and pg_search. It explains why basic ILIKE queries degrade as datasets grow, how PostgreSQL full-text search uses tsvector, tsquery, GIN indexes, and the @@ operator, and where native search falls short in large-scale performance, relevance ranking, and search quality.

## Source excerpt

Implementing text search in Postgres is trivial. You can do it as simply as this: But like most simple things in SQL, it's only simple when your data is simple--when you hit anything approaching scale, the simple things become hard. Full-text search is precisely one of these cases...
