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