• If you are trying to use Boolean operators, they must be ALL CAPS: ((zhang yan) OR (wang yan)) ((((tan hua) OR (tuan hua))) OR (wang hua)) rene ten jim kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) or (wang yan)) ((((tan hua) OR (tuan hua))) or (wang hua)) rene ten jim kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yan) or (wang yan)) ((((tan hua) OR (tuan hua))) or (wang hua)) rene ten jim kong sar ;*.
