Qdrant

Qdrant란 무엇인가요?

Qdrant is an open-source vector search engine written in Rust. It is designed to help teams build AI retrieval systems that need fast similarity search, flexible filtering, and deployment options that range from cloud to self-hosted environments.

The product is positioned for production-grade AI search, including retrieval for RAG, AI agents, semantic search, recommendation systems, and analysis workflows. Its page emphasizes real-time indexing, efficient storage, and developer tools that make vector search practical to integrate and operate.

Expansive metadata filtering

Store metadata in JSON and apply advanced filters such as nested, text, geo, and has_vector filters when querying vectors.

Native hybrid search

Combine keyword and vector search in one query, with support for dense or sparse vectors and retrieval methods like BM25, SPLADE++, and miniCOIL.

Built-in multivector support

Use multiple vectors per object to make retrieval more expressive, flexible, and suitable for multimodal data.

One-stage filtering

Apply filters during HNSW traversal so results are filtered in one stage, aiming for high recall with low latency under complex conditions.

Full-spectrum reranking

Use score boosting, late interaction models such as ColBERT, and MMR to shape ranking and diversify results.

Developer-facing API and tooling

Work through REST, gRPC, official client libraries, and the built-in web UI for inspection and testing.

사용 사례

“RAG and GenAI”

Build retrieval-augmented generation pipelines that combine dense and sparse search, metadata filters, and fresh indexed data for context-rich answers.

“AI agents”

Create context-aware agents with persistent memory and fast similarity search for conversation state and task context.

“Semantic search”

Implement semantic search that returns relevant results based on intent rather than keyword matching alone.

“Recommendation systems”

Power recommendation systems with real-time similarity matching across large item sets and metadata-aware ranking.

“Data analysis and anomaly detection”

Detect anomalies by searching for patterns that deviate from normal behavior in operational or analytical data.

자주 묻는 질문
