• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky sang tao hoa. hieu ((va nay) OR (va cay)) tuc ((xa hanh) or (xa thanh)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky sang tao hoa. hieu ((va nay) OR (va cay)) tuc ((xa hanh) OR (xa thanh)) tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang tao hoa. hieu ((va nay) OR (va cay)) tuc ((xa hanh) or (xa thanh)) tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky sang tao hoa. hieu ((va nay) OR (va cay)) tuc ((xa hanh) or (xa thanh)) tai cua tre*.
