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