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