• If you are trying to use Boolean operators, they must be ALL CAPS: ((((fang yuan) OR (meng yuan))) OR (wang yan)) wang ((li chen) OR (jui chen)) pains long kong 7 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((fang yuan) or (meng yuan))) or (wang yan)) wang ((li chen) OR (jui chen)) pains long kong 7 ;~".
• Adding a wildcard symbol may retrieve word variants: ((((fang yuan) or (meng yuan))) or (wang yan)) wang ((li chen) OR (jui chen)) pains long kong 7 ;*.
