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