• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programaaacion visual codigo.\"))) OR (\"programaaatica el codigo.\"))~".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programaaacion visual codigo. ))) OR ( programaaatica el codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programaaacion visual codigo."))) OR ("programaaatica el codigo."))*.
