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