Just published a new blog post on Using RAG with AI Vector Search. I found that RAG can be daunting for people new to AI. Hopefully this post will help explain how it all works together and show how powerful AI Vector Search can be. blogs.oracle.com/database/us…

A new blog post on using hybrid vector indexes in AI Vector Search is now available here: blogs.oracle.com/database/po…. This is the third type of index that I have blogged about and has some advantages and ease of use features over just HNSW or IVF vector indexes.

Just published a new AI Vector Search post about IVF Vector Indexes. If your vector index is too large to fit in-memory then an IVF Vector Index will still allow you to get great performance for your approximate similarity searches: blogs.oracle.com/database/po…

Just posted a new blog on Getting Started with Oracle Database 23ai Vector Search. I find it fascinating that AI Vector Search enables searching on the semantic meaning of data rather than just the actual words. Hopefully you will too. blogs.oracle.com/database/po…
