Strategy to use for recommendations, either "average_vector" or "best_score". The default is "average_vector". The "average_vector" strategy will construct a single average vector from the positive and negative samples then use it to perform a pseudo-search. The "best_score" strategy is more advanced and navigates the HNSW with a heuristic of picking edges where the point is closer to the positive samples than it is the negatives.
