• If you are trying to use Boolean operators, they must be ALL CAPS: dong sein das ((yulu cheng) OR (yu cheng)) ((ming hui) OR (ming hua)) wang yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong sein das ((yulu cheng) or (yu cheng)) ((ming hui) OR (ming hua)) wang yue ;~".
• Adding a wildcard symbol may retrieve word variants: dong sein das ((yulu cheng) or (yu cheng)) ((ming hui) OR (ming hua)) wang yue ;*.
