Could you utilize MMR for UmpireBot - MLB Rules For Baseball

[abishpius]

Would it be possible to update the document search to utilize MMR (Max marginal relevance) instead of this?
relevant_context = search_elements(question, k = 1 + 3int(10(1-closest_match)))

I want to say it will be better at grabbing more context for more ambiguous questions, but will leave final decision to you.
