• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yang))) OR (dong sign)) ya ((hua rest) OR (hua ren)) yang thi wong shiu ;.
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (wang yang))) or (dong sign)) ya ((hua rest) or (hua ren)) yang thi wong shiu ;*.
