Perhaps you should try some spelling variations:
banken bond » bank bond, banken und, banken von
liang ying » liang liying, huang ying, zhang ying
wang jing » wang ning, wang liang, wang yang
boost der » bist der, boom der
trost der » test der, droht der, rest der
bond sale » bond sales, bond rate

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: wang ((liang ying) OR (wang jing)) can ((boost der) OR (trost der)) banken bond sale ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang ying) or (wang jing)) can ((boost der) OR (trost der)) banken bond sale ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang ying) or (wang jing)) can ((boost der) OR (trost der)) banken bond sale ;*.
