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