• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (tu sach)) ha tang van hoe. hieu ve cham tuc ((xa tinh) OR (ca tinh)) di cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ha tang van hoe. hieu ve cham tuc ((xa tinh) OR (ca tinh)) di cau triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (tu sach)) ha tang van hoe. hieu ve cham tuc ((xa tinh) OR (ca tinh)) di cau triet*".
