Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
cote 4.1 » code 4.1, vote 4.1, case 4.1
4.1 when » 6.1 when, 4.1 what, 4.1 why
dong de » dong di, don de, dong wei
de cote » de conte, du cote, de code
when so » when do, when co, when soft
so ging » so fing
yang yi » yang jui
yang xi » yang jui

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: dong de cote 4.1 when so ging ((((yang yang) OR (yang yi))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong de cote 4.1 when so ging ((((yang yang) or (yang yi))) or (((yang di) or (yang xi)))) ;*.
