• If you are trying to use Boolean operators, they must be ALL CAPS: (( guias ((5 les) OR (2 les)) transformations used can ) OR ( guias de file transfer fair a ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias ((5 les) OR (2 les)) transformations used can ) or ( guias de file transfer fair a ))*".
