Yandex B2B Tech Integrates Hybrid Full-Text and Vector Search in Single YDB Query

Yandex B2B Tech has added hybrid search to its YDB database, allowing full-text and vector approaches to run together inside one SQL query. The update helps small and medium businesses as well as large corporations locate exact document identifiers while also matching semantic meaning in descriptions, even when wording differs. Full-text search handles precise elements such as policy numbers, codes, and names, whereas vector search identifies conceptual similarity. Results from both methods are merged and ranked within the same transaction, keeping all data inside a single database instance. This removes the need to maintain a separate search engine and vector store or to reconcile information between them. The technology is aimed at chatbots, recommendation systems, and AI assistants that process technical content where both exact codes and human-readable problem descriptions matter equally. Hybrid search is now available in the on-premises YDB 26.3 release and in the cloud-based Managed Service for YDB.
