• Performing a fuzzy search may retrieve terms with similar spellings: qian gong liutang di zhen yong ((((hong rong) OR (hong jong))) or (hong hong)) su ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian gong liutang di zhen yong ((((hong rong) OR (hong jong))) OR (hong hong)) su ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian gong liutang di zhen yong ((((hong rong) OR (hong jong))) or (hong hong)) su ;*".
