Perhaps you should try some spelling variations:
"nigeria language" » "nigerian languages", "sumerian language", "media language"
"vulgare langue" » "vulgar tongue"
"bulgare langue" » "bulgarie langue", "bulgarien langue", "bulgaria langue"

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: (((("bulgare langue") OR ("vulgare langue"))) OR ("nigeria language")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"bulgare langue\") OR (\"vulgare langue\"))) or (\"nigeria language\"))".
• Removing quotes may allow a broader search: (((( bulgare langue ) OR ( vulgare langue ))) or ( nigeria language )).
• Adding a wildcard symbol may retrieve word variants: (((("bulgare langue") OR ("vulgare langue"))) or ("nigeria language"))*.
