    • setOutputFields

      public void setOutputFields(String[] fields)
      Set the scalar fields to return.
      Parameters:
      fields - field names; null returns all fields, an empty array returns only the primary key / system columns

    • setHNSWParams

      public void setHNSWParams(HnswQueryParams params)
      Set HNSW query parameters. Ownership transfers to this query.

    • setIVFParams

      public void setIVFParams(IvfQueryParams params)
      Set IVF query parameters. Ownership transfers to this query.

    • setFlatParams

      public void setFlatParams(FlatQueryParams params)
