• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky tang xa hoi. hieu vien bach xuc gia thanh va ((((cuu tre) OR (cau tren))) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang xa hoi. hieu vien bach xuc gia thanh va ((((cuu tre) OR (cau tren))) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang xa hoi. hieu vien bach xuc gia thanh va ((((cuu tre) OR (cau tren))) or (cua te))*".
