• If you are trying to use Boolean operators, they must be ALL CAPS: tang jing fang yuan ((((dan yang) OR (yang yang))) OR (tan yang)) jin fang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tang jing fang yuan ((((dan yang) OR (yang yang))) or (tan yang)) jin fang hay ;~".
• Adding a wildcard symbol may retrieve word variants: tang jing fang yuan ((((dan yang) OR (yang yang))) or (tan yang)) jin fang hay ;*.
