• Performing a fuzzy search may retrieve terms with similar spellings: (("program _ codigo.") OR ((("programasa parallel codigo.") OR ("programaasa de codigo."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program _ codigo.\") OR (((\"programasa parallel codigo.\") OR (\"programaasa de codigo.\"))))".
• Removing quotes may allow a broader search: (( program _ codigo. ) OR ((( programasa parallel codigo. ) OR ( programaasa de codigo. )))).
• Adding a wildcard symbol may retrieve word variants: (("program _ codigo.") OR ((("programasa parallel codigo.") OR ("programaasa de codigo."))))*.
