You can use a managed vector database to run production RAG pipelines without self-hosting. It handles storing, indexing, and querying embeddings at scale, removing the operational burden of maintaining your own search infrastructure.

Hybrid search combines dense and sparse vectors to improve recall by matching both semantic meaning and exact keywords. You need it when pure semantic search misses critical keyword overlaps in user queries across large document collections.

You isolate user data in multi-tenant vector search by using namespaces and metadata filters. This separates users, environments, and content categories within the same index, ensuring queries only return results from the correct tenant.

Yes, you can apply metadata filters alongside semantic similarity queries. This allows you to restrict vector search results to specific content categories or user attributes, enabling fast personalized answers in production retrieval workflows.

Yes, managed vector search supports recommendation systems with low-latency query patterns. You can index user activity and content embeddings, then query the appropriate namespace to retrieve relevant recommendations quickly at scale.

Self-hosting a vector database requires building and maintaining indexing, querying, and scaling infrastructure yourself. A managed service removes this operational burden, providing optimized low-latency hybrid query patterns without requiring manual infrastructure management.
