• If you are trying to use Boolean operators, they must be ALL CAPS: dong hoang fan than bau yang ((aid how) OR (((among hong) OR (kong hong)))) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hoang fan than bau yang ((aid how) or (((among hong) OR (kong hong)))) hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong hoang fan than bau yang ((aid how) or (((among hong) OR (kong hong)))) hai ;*.
