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