      .. versionadded:: 2017.7.0
  
      Update the mine data on a certain group of minions.
  
      tgt
          Which minions to target for the execution.
  
      tgt_type: ``glob``
          The type of ``tgt``.
  
      clear: ``False``
          Boolean flag specifying whether updating will clear the existing
          mines, or will update. Default: ``False`` (update).
  
      mine_functions
          Update the mine data on certain functions only.
          This feature can be used when updating the mine for functions
          that require refresh at different intervals than the rest of
          the functions specified under ``mine_functions`` in the
          minion/master config or pillar.
  
      CLI Example:
  
      .. code-block:: bash
  
          salt-run mine.update '*'
          salt-run mine.update 'juniper-edges' tgt_type='nodegroup'
      '''
      ret = __salt__['salt.execute'](tgt,
                                     'mine.update',
                                     tgt_type=tgt_type,
                                     clear=clear,
                                     mine_functions=mine_functions)
      return ret
