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