Perhaps you should try some spelling variations:
first ideal » first deal, first real
one first » come first, one fast, one fits
ideal der » ideal des
wang yang » wang yan, wang liang, wang yanling
tang yun » yang yun, chang yun, fang yuan
der cas » der casa, der case, der ca
yang xi » yang jui
yang yi » 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: one first ideal der cas ((((yang xi) OR (wang yang))) OR (yang di)) ((tang yun) OR (yang yi)) ;*.
