• If you are trying to use Boolean operators, they must be ALL CAPS: qian yin fang wai chung ((dong hoang) OR (((tong song) OR (song seng)))) kong heng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yin fang wai chung ((dong hoang) or (((tong song) OR (song seng)))) kong heng ;~".
• Adding a wildcard symbol may retrieve word variants: qian yin fang wai chung ((dong hoang) or (((tong song) OR (song seng)))) kong heng ;*.
