Vespa is an open-source platform for real-time vector search, text search, and machine-learned ranking, developed by Yahoo (now Oath/Verizon Media). It combines large-scale serving capabilities with the flexibility of a full-featured search engine, making it suitable for use cases such as recommendation systems, semantic search, personalized feeds, and large-scale retrieval-augmented generation (RAG) pipelines.
Unlike many vector-only databases, Vespa supports hybrid search (combining vector similarity with structured filtering, text relevance, and ML models), enabling complex query logic and custom ranking. It’s optimized for low-latency inference at scale and supports indexing, filtering, and ranking billions of documents in production environments.
Key benefits include:
Unified support for dense vector search, keyword search, and ML ranking
Real-time updates, filtering, and aggregation at query time
Production-ready for large-scale, low-latency applications
What are the main features of Vespa?
Hybrid search engine for vectors, text, and structure
Vespa is designed for flexible, large-scale search across different data modalities.
Combine dense vector similarity with keyword relevance and structured filters
Query language supports complex logical conditions, scoring functions, and boosting
Useful for semantic search, e-commerce, question answering, and personalization
Built-in machine-learned ranking (MLR)
Vespa natively supports ranking using machine learning models, directly during search.
Deploy linear, tree-based, or ONNX models for scoring
Apply inference at query time across thousands of candidate results
Rerank results using custom relevance logic or neural models
Real-time indexing and updates
Vespa provides real-time ingestion and updates without downtime.
Documents and vectors can be updated individually or in bulk
