• Performing a fuzzy search may retrieve terms with similar spellings: te sach y sang ma hoi. ((hieu van) or (hieu va)) cam duc va dinh lam ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y sang ma hoi. ((hieu van) OR (hieu va)) cam duc va dinh lam ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang ma hoi. ((hieu van) or (hieu va)) cam duc va dinh lam ((cua tre) OR (cuu tre))*".
