FAQPage Schema

How do vector databases work for similarity search in AI applications?▼

Vector databases enable similarity search by converting data into embeddings and comparing distance metrics. They use indexing strategies like HNSW, IVF, and PQ to efficiently query nearest neighbors for AI applications.

What is the best vector database for RAG production deployments?▼

Choosing the best vector database for RAG depends on your scale and hosting needs. You can evaluate Pinecone, Qdrant, Chroma, pgvector, Weaviate, and Milvus based on their specific features and production capacity.

How do I implement similarity search and filtering using Python in vector databases?▼

You can implement similarity search and filtering using Python by utilizing code snippets for indexing and querying. These examples demonstrate common operations to retrieve and filter vector data efficiently.

When should I use HNSW versus IVF indexing for my vector database?▼

You should choose between HNSW and IVF indexing based on your latency and resource constraints. HNSW prioritizes query speed, while IVF combined with PQ optimizes memory usage for large-scale vector data indexing.

Does pgvector support hybrid search for RAG applications?▼

Yes, you can implement hybrid search alongside capacity planning considerations. The guide covers production hybrid search techniques across supported databases like pgvector to optimize RAG performance.
