• If you are trying to use Boolean operators, they must be ALL CAPS: ((wei yang) OR (wang yang)) wang hua rent sharing hays ((song sau) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wei yang) or (wang yang)) wang hua rent sharing hays ((song sau) OR (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wei yang) or (wang yang)) wang hua rent sharing hays ((song sau) OR (kong sar)) ;*.
