• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (yang yang))) OR (yan guan)) ya hua pei yang ((jie song) OR (li song)) shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (yang yang))) or (yan guan)) ya hua pei yang ((jie song) or (li song)) shu ;*.
