• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (((((dong yang) OR (yang yang))) OR (hong hong)))) ya hua chen tan minh congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((((dong yang) OR (yang yang))) or (hong hong)))) ya hua chen tan minh congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (((((dong yang) OR (yang yang))) or (hong hong)))) ya hua chen tan minh congo shu ;*.
