      Description

      The current LSH implementation only supports AND-OR amplification. We need to discuss the following questions before we goes to implementations:
      (1) Whether we should support OR-AND amplification
      (2) What API changes we need for OR-AND amplification
      (3) How we fix the approxNearestNeighbor and approxSimilarityJoin internally.
