• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (wang yang)) ka hua fei huang ((bin dang) OR (bin zhang)) (hai OR hadi) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong hoang) or (wang yang)) ka hua fei huang ((bin dang) OR (bin zhang)) (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (wang yang)) ka hua fei huang ((bin dang) OR (bin zhang)) (hai or hadi) ;*.
