Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung gun » young eun
en plaine » en laine, en place, et laine
longer do » longer _, longer a
en panne » et anne
gun jan » yun jang
long do » long d, long du, long ago

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: lang hyoung gun jan ((en panne) OR (en plaine)) jiu ((long do) OR (longer do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung gun jan ((en panne) OR (en plaine)) jiu ((long do) or (longer do)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung gun jan ((en panne) OR (en plaine)) jiu ((long do) or (longer do)) ;*.
