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