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