Vector Search
Vector search improves ways to interact with data and power important use cases like aiding natural language chatbots and sophisticated enterprise hybrid search that combines range, text, and vector predicates in one.

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 GenAI 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.
Don’t let these vector search challenges slow you down
Complexity
There is no need to use a separate database for vector search, adding 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 GenAI apps without feeding corporate data to public models and deliver users accurate and up-to-date results.
Scalability
Avoid needing to architect your app when it moves into the real world. Choose a vector database solution that scales globally with millisecond response times.
Vector search key capabilities
Building powerful vector and GenAI-based applications requires a powerful database platform with a differentiated architecture that is fast, affordable, versatile, and as easy as SQL. Couchbase helps developers build apps using vector search and working with LangChain and LlamaIndex to leverage the artificial intelligence ecosystem.
Single platform for agentic applications
Build modern applications, supporting GenAI, RAG, and agents at scale, while minimizing privacy concerns and latency.
Hybrid search for the real world
Support vector, full-text, ranges, predicate, and geolocation with a single SQL query and a single index, for real-world use cases with low latency.
Highly scalable
Benefit from Couchbase’s industry-leading price performance and ability to flexibly grow Search and Index Services to any scale.
Cloud-to-edge support
With vector search in the cloud and on-device, you gain the cloud scale required for GenAI and the edge processing to make it effective.
Similarity search, hybrid search
Similarity is a powerful tool for users to find products and information, but many real-world scenarios have users wanting to search across a variety of methods, like text, geolocations, ranges, and include operational data too. Couchbase lets developers build powerful search functionality to delight users.
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 GenAI 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.
What customers are saying
“With search integrated into Couchbase, we can seamlessly search all this data and derive relevance-based intelligence using a single data platform.”
“Couchbase Search allows us to deliver customer search results from extremely large data sets very efficiently.”
“Couchbase is a trifecta of value. We get more features, save time, and spend less money all at once.”
“Couchbase provides a solution no others do. It gives us the modularity we need with immediate operational simplicity, high performance, and scalability.”
