Universal Containers is implementing a Retrieval-Augmented Generation (RAG) solution where the knowledge store contains Spanish...

The correct answer is C. In a multilingual RAG design, the embedding model must support semantic similarity across the languages involved in both the source content and user queries. Since the articles are in Spanish and users may ask questions in French or English, selecting the multilingual-e5-large embedding model broadly for the search index is the correct approach. Option A and Option B are too narrow because each excludes one of the languages in the complete requirement. The retriever does not simply match keywords; it compares vector representations of the query and indexed chunks. A multilingual embedding model improves cross-language retrieval by placing semantically similar text from different languages closer in vector space. Salesforce Data 360 search index guidance identifies multilingual content and embedding-model selection as key retrieval considerations.
