Comment # 2 on bug 64177 from Eugenio Parodi

This new extended searching criteria are ok.
Just one note regarded:
      -   "is not possible to define searches where
           the *same* value must meet different criteria"
This meas that a query like this is not allowed?

  [ 'or',
    [ 'and',
      [ 'begins_with', 'structured-name/given' , 'a' ],
      [ 'begins_with', 'structured-name/family', 'b' ]
    ],
    [ 'and',
      [ 'begins_with', 'structured-name/given' , 'b' ],
      [ 'begins_with', 'structured-name/family', 'a' ]
    ]
  ]

If not, can it be accepted in the future?
Thanks.
