• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((dang xa) or (dong ha)) hoi. hieu ve ((cham cuc) OR (pham chuc)) ban tinh lao cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((dang xa) OR (dong ha)) hoi. hieu ve ((cham cuc) OR (pham chuc)) ban tinh lao cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((dang xa) or (dong ha)) hoi. hieu ve ((cham cuc) OR (pham chuc)) ban tinh lao cua tre*".
