• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hong wang) OR (hong jong))) OR (dong hoang)) yang hui rent yan ((thi hong) OR (tan hong)) yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hong wang) OR (hong jong))) or (dong hoang)) yang hui rent yan ((thi hong) or (tan hong)) yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((hong wang) OR (hong jong))) or (dong hoang)) yang hui rent yan ((thi hong) or (tan hong)) yu ;*.
