• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y dang ma hoi. hieu ((va cham) OR (va tham)) loc va nhan tai ((cuu tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang ma hoi. hieu ((va cham) OR (va tham)) loc va nhan tai ((cuu tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang ma hoi. hieu ((va cham) OR (va tham)) loc va nhan tai ((cuu tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach y dang ma hoi. hieu ((va cham) OR (va tham)) loc va nhan tai ((cuu tre) or (cua te))*.
