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