• Performing a fuzzy search may retrieve terms with similar spellings: thu sach 7 tang ((van hoi) OR (van hoe)). hieu ve ((cham lo) or (cam lo)) va thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach 7 tang ((van hoi) OR (van hoe)). hieu ve ((cham lo) OR (cam lo)) va thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach 7 tang ((van hoi) OR (van hoe)). hieu ve ((cham lo) or (cam lo)) va thanh vai cuu tre*".
