How does Qdrant handle large-scale vector datasets?

It utilizes HNSW for efficient indexing and offers various quantization methods to reduce memory footprints by up to 4x while maintaining high search accuracy.

What makes Qdrant different from other vector databases?

Qdrant is written in Rust for high performance and safety, offering superior horizontal scaling, complex filtering during search, and flexible multi-vector support per point.

What distance metrics does Qdrant support?

Qdrant supports Cosine, Euclidean, Dot Product, and Manhattan distance metrics to accommodate various embedding models and use cases.

Can I use this with LangChain or LlamaIndex?

Absolutely. This skill includes specific code samples and best practices for integrating Qdrant with popular RAG frameworks like LangChain and LlamaIndex.

Does this skill support hybrid search?

Yes, it provides implementation patterns for hybrid search that combine dense vector similarity with sparse vector (BM25/SPLADE) search and metadata filtering.
