• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (dong hoang)) ala yu cheng rong ((chen wang) OR (chen yang)) siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (dong hoang)) ala yu cheng rong ((chen wang) OR (chen yang)) siu ;*".
