• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (hong wang)) wang ((hua chen) OR (jui chen)) yang jin wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (hong wang)) wang ((hua chen) OR (jui chen)) yang jin wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (hong wang)) wang ((hua chen) OR (jui chen)) yang jin wong sau ;*.
