• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program _ codigo.\") OR (((\"programacion visudddal codigo.\") OR (\"programacion el codigo.\"))))*".
• Removing quotes may allow a broader search: (( program _ codigo. ) OR ((( programacion visudddal codigo. ) OR ( programacion el codigo. ))))*.
