Best For
Hybrid search at scale on top of mature search infrastructure — combine BM25, ELSER sparse vectors, and dense vectors in one query
High-performance vector search with rich payload filtering — Rust-written, predictable latency, and a clean self-hosted path
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
No built-in embedding generation — bring your own embeddings; managed cloud is younger than Pinecone's; fewer turnkey RAG modules than Weaviate
