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