• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong cao) OR (dong bin))) OR (dong skin)) ya ((hua gene) OR (hua ren)) yuan tan hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong cao) or (dong bin))) or (dong skin)) ya ((hua gene) OR (hua ren)) yuan tan hong shu ;*".
