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