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