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