Perhaps you should try some spelling variations:
demands during » remarks during
water demands » water demand
zhang bank » zhang fan, zhang yan, zhang fang
li zhang » _ zhang
bank run » bank runs
bonn a » bonn am, bonn _, bon a
von a » von h, von i, von r
von f » von h, von i, von r

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: li zhang bank run water demands during ((((von a) OR (von f))) OR (bonn a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "li zhang bank run water demands during ((((von a) OR (von f))) or (bonn a)) ;~".
• Adding a wildcard symbol may retrieve word variants: li zhang bank run water demands during ((((von a) OR (von f))) or (bonn a)) ;*.
