• If you are trying to use Boolean operators, they must be ALL CAPS: wang yuan ka chai dan yang jin ((((shang hai) OR (shang kai))) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuan ka chai dan yang jin ((((shang hai) OR (shang kai))) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuan ka chai dan yang jin ((((shang hai) OR (shang kai))) or (zhong tai)) ;*.
