• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan ka) OR (yuan kai)) ((yu cheng) OR (jui chen)) ((chan eng) OR (chan ming)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan ka) OR (yuan kai)) ((yu cheng) or (jui chen)) ((chan eng) or (chan ming)) wong sau ;*".
