Why state-of-the-art search models fail on complex queries — and what to build instead

Your AI Search works until it doesn’t.

This article discusses the limitations of current AI search models, specifically highlighting how vector embeddings struggle with complex queries due to fundamental mathematical constraints. It explains that despite advancements in embedding models, there are inherent retrieval tasks that cannot be effectively solved, regardless of improvements in data size or training duration. The piece further outlines three key measurements for evaluating embedding models, demonstrates their failures through a specific dataset called LIMIT, and provides insights into alternative approaches for enhancing performance in AI retrieval systems.
