At the end, the course points out the known limitations of the current hybrid search approach: spelling tolerance is not included in the scheme; expanding semantic coverage can only be done by increasing the number of embedded articles; long articles need to be split into small chunks and then embedded to reach content beyond the beginning; a re-ranker can be introduced to re-rank the top results.
