• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (zhang yan)) ((wang hui) OR (wang wei)) ying yang aid zhong tai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) or (zhang yan)) ((wang hui) OR (wang wei)) ying yang aid zhong tai ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (zhang yan)) ((wang hui) OR (wang wei)) ying yang aid zhong tai ;*.
