Best For
Hybrid search at scale on top of mature search infrastructure — combine BM25, ELSER sparse vectors, and dense vectors in one query
Hybrid RAG with built-in vectorizer modules, generative search, and strong multi-tenancy — runs anywhere from laptop to managed cloud
Limitations
Heavier and more memory-hungry than purpose-built vector engines; license is no longer pure Apache 2.0; vector-only workloads are overserved by Elasticsearch's full feature surface
Resource-hungry compared to Qdrant or Chroma; module configuration has a learning curve; some advanced replication features are cloud-only
