Abstract:
Vector search alone quietly fails on certain kinds of queries, like exact error codes, product IDs, and rare terms, while keyword search misses results phrased differently from the query. Hybrid search solves this by running lexical and dense vector search over the same data and fusing the results, so a confident hit from either retriever still ranks well. It has become the standard retrieval approach for RAG, and increasingly for enterprise search. If your data already lives in Db2, you already have the building blocks for hybrid search over your own data. This session shows how to build it end to end inside Db2 12.1.5, from ingestion to query: one chunk table, two representations, two indexes, and reciprocal rank fusion expressed in SQL. You'll leave understanding the full ingestion-to-query pipeline, including why a strong single-retriever hit is never penalized. Aimed at engineers and architects on the Db2 platform who want AI-powered retrieval without standing up a separate vector database.
