• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang liang)) yan hua ren ((sang minh) OR (((yang li) OR (yang lin)))) tong shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang liang)) yan hua ren ((sang minh) or (((yang li) or (yang lin)))) tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang liang)) yan hua ren ((sang minh) or (((yang li) or (yang lin)))) tong shui ;*.
