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