• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((than china) OR (wuhan china)) ((dan yang) OR (tan yang)) li gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((than china) or (wuhan china)) ((dan yang) OR (tan yang)) li gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((than china) or (wuhan china)) ((dan yang) OR (tan yang)) li gang hai ;*.
