• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu sach - hanh ((trang cua) or (trung cua)) ((dung huong) OR (dong huong)) dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - hanh ((trang cua) OR (trung cua)) ((dung huong) OR (dong huong)) dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh ((trang cua) or (trung cua)) ((dung huong) OR (dong huong)) dan than cau*".
