• If you are trying to use Boolean operators, they must be ALL CAPS: ((xuan thang) OR (huang chang)) mae hua ren wang jing ((wong yue) OR (wang yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((xuan thang) or (huang chang)) mae hua ren wang jing ((wong yue) OR (wang yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((xuan thang) or (huang chang)) mae hua ren wang jing ((wong yue) OR (wang yue)) ;*.
