Vector Search

Couchbase’s breakthrough vector search features support billion-scale vector storage and search capabilities for applications with incredible performance and accuracy. Multiple vector index type options provide teams with the best results aligned to their use case. Deliver safer AI results with RAG and vector search at a huge scale.

What is vector search used for in a database?

Vector search delivers nearest-neighbor results without needing a direct match. Text, images, audio, and video are converted to mathematical representations and used for semantic searching or overcoming AI challenges using the retrieval-augmented generation (RAG) framework. At the enterprise level, vector search is commonly used for powerful, natural language chatbots, sophisticated search that delivers a hybrid search combining range, text, and vector predicates, and data analysis spotting similarity and anomalies. In Couchbase 8.0, we introduce Hyperscale and Composite vector indexes to improve RAG accuracy at scale without hurting performance or cost of operations.

Don’t let these vector search challenges slow you down

Complexity

There is no need to use a separate database for vector search, which adds complexity, administration, cost, and latency of the overall app.

Latency

Returning results as fast as possible is critical to users. Extra hops and poor indexing kill user experience.

Security

Build AI apps without feeding corporate data to public models and deliver users accurate and up-to-date results.

Scalability

Couchbase is proven to handle billions of vectors with millisecond response times, so your application can scale globally without limits.

Vector search key capabilities

Building powerful vector and AI-based applications requires a powerful database platform with a differentiated architecture that is fast, affordable, and versatile.

  • AI Data Plane for agentic applications

    Build modern applications, supporting AI, RAG, and agents at scale, while minimizing privacy concerns and latency.

  • Unmatched indexing flexibility

    Couchbase uniquely offers three vector indexing options to match your performance, recall, cost, and query needs.

  • Billions-scale performance

    Billion-scale vector search for real-time AI context at scale with a memory-first architecture and flexible indexing services.

  • Cloud-to-edge support

    With vector search in the cloud and on-device, you gain the cloud scale required for AI and the edge processing to make it effective.

Similarity is a powerful tool, but real-world scenarios require hybrid search across text, geolocations, ranges, and operational data. With multiple indexing options, developers can precisely tune their hybrid search strategy for optimal performance and relevance.

Agentic and RAG apps

AI agents will add a new level of sophistication and reasoning to how users will interact with an organization and their data. Using RAG, teams can make AI apps safer, more accurate, and up to date.

Fraud and anomaly detection

By converting user behavior and transactions into vectors, those patterns can be compared to other similar vector representations that might indicate fraud. Vector search is effective in handling high-dimensional data and similarity matching.

Mobile vector apps

Running vector search in mobile and embedded devices comes with all the benefits of edge computing including millisecond response times, reliability, availability even without the internet (“offline-first”), bandwidth savings, and most importantly, customized responses without compromising on data privacy.

Vector search FAQ

Get quick answers to questions about vector search, databases, and more.

Couchbase is a multimodel platform that combines high-performance vector search with text, geo-spatial, and other search techniques, eliminating the need for a separate, standalone vector database.

Couchbase supports three primary index types: Hyperscale for billion-scale datasets, Composite for high-speed filtered searches, and Search for hybrid semantic-keyword queries.

Native support for vector search on mobile devices is available in Couchbase Lite, which enables offline-first vector search on iOS, Android, and IoT platforms.

Couchbase supports RAG pipelines by serving as a dedicated vector store to automate embedding creation and indexing, ensuring LLMs have access to accurate, private enterprise context.
