• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((oanh tran) OR (anh tran)) hua irene yang ((jie song) OR (kim song)) sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((oanh tran) or (anh tran)) hua irene yang ((jie song) OR (kim song)) sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((oanh tran) or (anh tran)) hua irene yang ((jie song) OR (kim song)) sam ;*.
