const SEARCH_GROUNDING_INSTRUCTION: &str = "\n\nSearch the course material with the azure_ai_search tool before answering, and ground your answer in the results with citations. Put only what you want to find in the query; the search is already limited to this course, so don't include the course name. Searching more than once is fine when it helps — to cover distinct sub-questions or angles, to refine when the first results don't answer, or when a follow-up or new instruction needs material you don't already have. When one search already answers, stop there. If you need more information about a specific document or a topic covered in it, use the document_lookup tool to retrieve the full document. Skip searching only for messages that don't need course material, like greetings or thanks. If you need more information about the course, like what pages and chapters are in it, use the course_structure tool.";Expand description
Appended to the system prompt when course-material search is enabled, to ground answers in retrieved course material.
