Perhaps you should try some spelling variations:
come first » comes first, cover first
first das » first days, first day, first case
wang yang » wang yan, wang liang, wang yanling
ying jin » yang jin, jing ji, yang jie
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
buch ce » buch cd, buch le, buch der
yang xi » yang di, yang yi

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: come first das buch ce ((((ying jin) OR (wang yang))) OR (yang xi)) ((yang jun) OR (yang jui)) ;~.
• Adding a wildcard symbol may retrieve word variants: come first das buch ce ((((ying jin) or (wang yang))) or (yang xi)) ((yang jun) or (yang jui)) ;*.
