• If you are trying to use Boolean operators, they must be ALL CAPS: wang changing face a join ((kang minh) OR (((song min) OR (gong min)))) congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang changing face a join ((kang minh) or (((song min) OR (gong min)))) congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang changing face a join ((kang minh) or (((song min) OR (gong min)))) congo shu ;*.
