A recent industry survey found that inaccuracy is now the most-cited AI risk as adoption scales, and for agents that act iteratively on what they retrieve, one bad result compounds into a chain of increasingly expensive mistakes. This session looks at how combining full-text, vector, and hybrid search — running natively on live, operational data — closes that gap, plus a conversation with CVS on what accurate retrieval actually looks like in production.
