SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires qdrant-client, and includes references (resource) components.

What problem does it solve? Building production RAG and semantic search systems requires fast nearest neighbor search over large embedding collections with metadata filtering, which standard databases cannot handle efficiently. ## Core Features & Use Cases - Vector Search with Filtering: Perform nearest neighbor search with dense, sparse, and multi-vector support combined with rich payload filtering. - Production Scaling: Use HNSW indexing, scalar/product/binary quantization, sharding, and replication for large-scale deployments. - RAG Framework Integration: Connect with sentence-transformers, LangChain, and LlamaIndex for retrieval pipelines. - Use Case: Index thousands of embedded documents into a Qdrant collection, then retrieve the top-k most relevant passages filtered by category to ground an LLM's answers. ## Quick Start Set up a Qdrant collection and index my documents so I can run semantic search queries with metadata filters.

Frequently Asked Questions about qdrant-vector-search

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform vector similarity search with Qdrant in Python?▼

Install qdrant-client, create a collection with VectorParams specifying dimension and distance metric, upsert PointStruct objects with vectors and payloads, then call client.search with a query vector and optional filters.

Qdrant vs Chroma vs FAISS for RAG applications?▼

Qdrant suits production RAG needing filtering, scaling, and on-premise control. Chroma is simpler for embedded use cases, FAISS offers maximum raw speed for batch research, and Pinecone fits fully managed zero-ops preferences.

Does Qdrant support hybrid search with sparse vectors?▼

Yes, Qdrant supports named vectors combining dense and sparse embeddings in one collection. Use Prefetch queries with FusionQuery for Reciprocal Rank Fusion to merge dense semantic and sparse keyword results.

Why is my Qdrant filtered search slow?▼

Slow filtered search usually means missing payload indexes on filtered fields. Create a payload index with client.create_payload_index for fields like category or timestamp, and consider enabling quantization for large collections.

How do I reduce Qdrant memory usage for large collections?▼

Enable scalar quantization for roughly 4x memory reduction, product quantization for 16x, or binary quantization for 32x. Also set on_disk_payload to true to store payloads on disk instead of RAM.

Can Qdrant run as a distributed cluster?▼

Yes, Qdrant supports distributed deployment using Raft consensus with sharding and replication. Configure shard_number and replication_factor when creating collections, and choose write consistency levels per operation.
