Perhaps you should try some spelling variations:
sudan der » suden der, sudan debt, sudan das
wang yang » wang yan, wang liang, wang yanling
low than » lower than, know than, low tax
yang yi » yang jui
yang xi » yang jui
3 sudan » _ sudan, im sudan, _ sudano
a among » 1 among, a amonn, era among
der a » der _, der e
gg 3 » gg b, ag 3, gg 2

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: ((((((yang yi) OR (yang xi))) OR (wang yang))) OR (yang di))gg 3 sudan der a among low than ;~.
• Adding a wildcard symbol may retrieve word variants: ((((((yang yi) or (yang xi))) or (wang yang))) or (yang di))gg 3 sudan der a among low than ;*.
