• Performing a fuzzy search may retrieve terms with similar spellings: su sach tao ((nhan bac) OR (nhanh bac)) ho. hieu ve cam xuc ((van hanh) or (van thanh)) va chua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tao ((nhan bac) OR (nhanh bac)) ho. hieu ve cam xuc ((van hanh) OR (van thanh)) va chua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tao ((nhan bac) OR (nhanh bac)) ho. hieu ve cam xuc ((van hanh) or (van thanh)) va chua tre".
• Adding a wildcard symbol may retrieve word variants: su sach tao ((nhan bac) OR (nhanh bac)) ho. hieu ve cam xuc ((van hanh) or (van thanh)) va chua tre*.
