• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - hanh ((((ctinh cua) OR (trinh cua))) or (tinh cua)) thong cong dan toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh ((((ctinh cua) OR (trinh cua))) OR (tinh cua)) thong cong dan toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((((ctinh cua) OR (trinh cua))) or (tinh cua)) thong cong dan toan tap*".
