What problem does it solve? Building production RAG and semantic search systems requires a vector database that handles low-latency similarity search, metadata filtering, and scaling, which is complex to implement from scratch. ## Core Features & Use Cases - Vector Search with Filtering: Store dense and sparse vectors with payloads, then run nearest-neighbor queries combined with keyword, range, geo, and full-text filters. - RAG Integration: Connect with sentence-transformers, LangChain, and LlamaIndex to build retrieval pipelines for question answering. - Production Scaling: Use quantization, payload indexing, sharding, replication, and snapshots for large collections and distributed deployments. - Use Case: Index a knowledge base of documents as embeddings, then retrieve the top-k most relevant passages filtered by category to ground an LLM's answers. ## Quick Start Use the qdrant skill to create a collection, upsert document embeddings, and run a filtered similarity search against a local Qdrant instance.
