Elasticsearch vs Plain Database Search: When Do You Actually Need It?

Where Plain Database Search Is Enough

For most projects with moderate data volume and simple search needs — finding a product by exact or near-exact name — a LIKE query or simple indexing in PostgreSQL or MySQL is entirely sufficient.

Where Elasticsearch Genuinely Makes a Difference

When you need advanced text search — ranking results by relevance, tolerating typos, or searching a very large volume of data at high speed — Elasticsearch makes a noticeable difference. Adding it to a small project usually increases infrastructure complexity without a real need for it.
