• If you are trying to use Boolean operators, they must be ALL CAPS: wang anh ((tuan vu) OR (thanh vu)) ((ren yuan) OR (meng yuan)) cheng wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang anh ((tuan vu) OR (thanh vu)) ((ren yuan) or (meng yuan)) cheng wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang anh ((tuan vu) OR (thanh vu)) ((ren yuan) or (meng yuan)) cheng wong sam ;*.
