Usage of distance during the search helps retrieval efficient.
Distance 0-0.2: Highly similar items. Use this range when you need very close matches (e.g., finding duplicate documents).
Distance 0.2-0.5: Moderately similar items. Useful when you want to find items that are related but not identical.
Distance 0.5-0.8: Weakly similar items. This range could be used for exploratory results where you want to include some diversity.
Distance 0.8-1.0: Dissimilar items. Typically, these items are unrelated, and you might filter them out unless dissimilarity is desirable (e.g., in anomaly detection).

Support distance ranges as parameter to Search.
