• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (wai yan)) tan ((hua gene) OR (hua ren)) ((yang jin) OR (huang lin)) hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (wai yan)) tan ((hua gene) or (hua ren)) ((yang jin) or (huang lin)) hong ghi ;*".
