Search Studocu courses when establishing or correcting course context. Prefer institution_id from search-institutions to scope results. Omit institution_id only when the institution is unknown: results then include catalog institution_id, and institution_name when Algolia has it. Do not require this before every document search. Structured results include course_id, name, code (nullable), institution_id, and optional institution_name. When talking to the user, present name, course code, and institution name only — do not show internal IDs. Auto-pick a clear top match; if the shortlist is ambiguous, ask the user to choose by name/code. Resolved IDs are conversation-scoped until a persistence capability owns them.
