• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang jiang) OR (wang yang)) tan hua rents yan ((than hong) OR (thang long)) than ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang jiang) or (wang yang)) tan hua rents yan ((than hong) OR (thang long)) than ;*".
