Do CSS Elasticsearch Clusters Support script dotProduct?

The Elasticsearch-native vector search function is provided via an X-Pack plugin, which is currently not integrated in CSS. This is why the native script dotProduct cannot be executed in Elasticsearch clusters created in CSS.

You are advised to use the vector search service provided by CSS. Based on an in-house developed vector search engine, CSS's vector search service is deeply integrated with the Elasticsearch plug-in architecture, featuring high-performance, high-precision, low-cost, and multi-modality. It offers an efficient, cost-effective solution to meet diversified, high-dimensional vector search needs. For more information, see Vector Search.
