• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ty lang xa hoi. thi van cam ((xuc va) or (thuc va)) hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty lang xa hoi. thi van cam ((xuc va) OR (thuc va)) hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ty lang xa hoi. thi van cam ((xuc va) or (thuc va)) hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ty lang xa hoi. thi van cam ((xuc va) or (thuc va)) hanh vai cua tre*.
