• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang daoping) OR (wang xiaobing)) tan chia ((un yang) OR (dan yang)) mind dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang daoping) OR (wang xiaobing)) tan chia ((un yang) or (dan yang)) mind dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang daoping) OR (wang xiaobing)) tan chia ((un yang) or (dan yang)) mind dang hari ;*.
