Perhaps you should try some spelling variations:
"indonesian languages" » "indonesia language", "indian languages", "melanesian languages"
"indonesian language" » "indian language"
"indostan language" » "hindustani language", "indian language", "hindoostanee language"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("indonesian languages") OR ("indostan language"))) OR ("indonesian language")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"indonesian languages\") OR (\"indostan language\"))) or (\"indonesian language\"))".
• Removing quotes may allow a broader search: (((( indonesian languages ) OR ( indostan language ))) or ( indonesian language )).
• Adding a wildcard symbol may retrieve word variants: (((("indonesian languages") OR ("indostan language"))) or ("indonesian language"))*.
