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