Vector Search Engine for the next generation of AI applications

Qdrant (read: quadrant) is a vector similarity search engine and vector database. It provides a production-ready service with a convenient API to store, search, and manage points—vectors with an additional payload Qdrant is tailored to extended filtering support. It makes it useful for all sorts of neural-network or semantic-based matching, faceted search, and other applications.

Qdrant is written in Rust 🦀, which makes it fast and reliable even under high load. See benchmarks.

With Qdrant, embeddings or neural network encoders can be turned into full-fledged applications for matching, searching, recommending, and much more!

Quick Start • Client Libraries • Demo Projects • Integrations • Contact

pip install qdrant-client

The python client offers a convenient way to start with Qdrant locally:

from qdrant_client import QdrantClient
qdrant = QdrantClient(":memory:") # Create in-memory Qdrant instance, for testing, CI/CD
# OR
client = QdrantClient(path="path/to/db")  # Persists changes to disk, fast prototyping

This is the recommended method for production usage. To run the container, use the command:

docker run -p 6333:6333 qdrant/qdrant

Now you can connect to this with any client, including Python:

qdrant = QdrantClient("http://localhost:6333") # Connect to existing Qdrant instance, for production

Qdrant offers the following client libraries to help you integrate it into your application stack with ease:

• Official: Go client
• Official: Rust client
• Official: JavaScript/TypeScript client
• Official: Python client
• Community: Elixir
• Community: PHP
• Community: Ruby
• Community: Java

• Quick Start Guide
• End to End Colab Notebook demo with SentenceBERT and Qdrant
• Detailed Documentation are great starting points
• Step-by-Step Tutorial to create your first neural network project with Qdrant

Unlock the power of semantic embeddings with Qdrant, transcending keyword-based search to find meaningful connections in short texts. Deploy a neural search in minutes using a pre-trained neural network, and experience the future of text search. Try it online!

There's more to discovery than text search, especially when it comes to food. People often choose meals based on appearance rather than descriptions and ingredients. Let Qdrant help your users find their next delicious meal using visual search, even if they don't know the dish's name. Check it out!

Enter the cutting-edge realm of extreme classification, an emerging machine learning field tackling multi-class and multi-label problems with millions of labels. Harness the potential of similarity learning models, and see how a pre-trained transformer model and Qdrant can revolutionize e-commerce product categorization. Play with it online!

For faster production-tier searches, Qdrant also provides a gRPC interface. You can find gRPC documentation here.

Qdrant enables JSON payloads to be associated with vectors, providing both storage and filtering based on payload values. It supports various combinations of should, must, and must_not conditions, ensuring retrieval of all relevant vectors unlike ElasticSearch post-filtering.

The vector payload accommodates diverse data types and query conditions, including string matching, numerical ranges, geo-locations, and more. These filtering conditions empower you to create custom business logic on top of similarity matching.

The query planner leverages stored payload information to optimize query execution. For instance, smaller search spaces limited by filters might benefit from full brute force over an index.

Utilizing modern CPU x86-x64 architectures, Qdrant delivers faster search performance on modern hardware.

Qdrant ensures data persistence with update confirmation, even during power outages. The update journal stores all operations, enabling effortless reconstruction of the latest database state.

As of v0.8.0, Qdrant supports distributed deployment. Multiple Qdrant machines form a cluster for horizontal scaling, coordinated through the Raft protocol.

Qdrant operates independently, without reliance on external databases or orchestration controllers, simplifying configuration.
