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