Perhaps you should try some spelling variations:
"apuntes generales" » "aspectos generales", "asientos generales", "manuales generales"
"artees generales" » "cortes generales", "caracteres generales", "arte general", "arteees generales"
"artes generales" » "cortes generales", "gastos generales", "cargos generales", "artees generales"
"art general" » "arte general"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("artes generales") or ((("artees generales") OR ("apuntes generales"))))) or ("art general"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("artes generales") OR ((("artees generales") OR ("apuntes generales"))))) OR ("art general"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"artes generales\") or (((\"artees generales\") OR (\"apuntes generales\"))))) or (\"art general\"))*".
• Removing quotes may allow a broader search: (((( artes generales ) or ((( artees generales ) OR ( apuntes generales ))))) or ( art general ))*.
