• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((anh tuan) OR (dinh tuan)) ((hua irene) OR (hua chen)) young john kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((anh tuan) OR (dinh tuan)) ((hua irene) or (hua chen)) young john kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((anh tuan) OR (dinh tuan)) ((hua irene) or (hua chen)) young john kong sar ;*.
