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