STR:

1. Add to LMS production settings - SEARCH_SKIP_ENROLLMENT_START_DATE_FILTERING = False
2. Go to <LMS_URL>/courses
3. Try to search courses

AR:
500 Error in networks

ER:
Search functionality works

Tech assumptions:
Following the migration from Elasticsearch to MeiliSearch, the set of filterable attributes has become static and hardcoded.
As a result, enabling default Open edX behavior that extends search filters (e.g., using enrollment_start) can cause MeiliSearch to reject the query, leading to a server error.
