• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) tu lang xa hoi. hieu ve cao suc va thanh va ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) tu lang xa hoi. hieu ve cao suc va thanh va ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) tu lang xa hoi. hieu ve cao suc va thanh va ((cua tre) or (cua triet))*".
