                               boolean ordered)

  - ### Method Detail

    - #### getOpDistance

          public int getOpDistance()

    - #### subQueriesOrdered

          public boolean subQueriesOrdered()

    - #### distanceSubQueryNotAllowed

          public String distanceSubQueryNotAllowed()

      Description copied from interface: `DistanceSubQuery`
      When distanceSubQueryNotAllowed() returns non null, the reason why the subquery is not allowed as a distance subquery is returned.
      When distanceSubQueryNotAllowed() returns null addSpanNearQueries() can be used in the creation of the span near clause for the subquery.
