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