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