• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang ma hoi. hieu va cam xuc ((ban danh) or (ban hanh)) vai ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang ma hoi. hieu va cam xuc ((ban danh) OR (ban hanh)) vai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang ma hoi. hieu va cam xuc ((ban danh) or (ban hanh)) vai ((cua triet) OR (cua viet))".
