PostgreSQL Trigrams Outshine Elasticsearch for 55M Record Fuzzy Search

This case study demonstrates why teams managing large databases should reconsider the automatic choice of Elasticsearch for search functionality. By leveraging PostgreSQL's native pg_trgm extension with GIN indexes, organizations achieve comparable search performance while eliminating operational overhead, infrastructure costs, and synchronization complexity. For projects requiring reliable fuzzy matching without advanced search features, PostgreSQL alone provides a more maintainable and cost-effective solution.
