Elasticsearch
Vector databasesThe widely deployed search engine, now with dense vector and hybrid search built in.
Elasticsearch is the long-established search engine, and it now does dense vector search alongside its traditional keyword search — which makes hybrid search, blending both, a native capability.
For organisations already running Elasticsearch for logs or search, it is a way to add retrieval without a new system or new operational skills.
Where it's ideally used
A fit when you already run Elasticsearch and want hybrid keyword-plus-vector search in the system you operate.
Where it doesn't fit
A heavy system to adopt purely for vector search — a dedicated vector database is leaner if that is all you need.
