• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang xa hoi. hieu va cao xuc va ((((hang thai) OR (hang tai))) or (hang hai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu va cao xuc va ((((hang thai) OR (hang tai))) OR (hang hai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu va cao xuc va ((((hang thai) OR (hang tai))) or (hang hai)) cua tre*".
