Best For
AI-native developer experience — the fastest path from `pip install` to a working RAG prototype, with a managed cloud when you're ready
Hybrid search at scale on top of mature search infrastructure — combine BM25, ELSER sparse vectors, and dense vectors in one query
Limitations
Younger than Pinecone or Weaviate at scale; fewer index tuning knobs (HNSW only); compliance certifications are still maturing
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
