• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ky dang ha noi. chieu ke chau phu ((du hanh) or (luu hanh)) dai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky dang ha noi. chieu ke chau phu ((du hanh) OR (luu hanh)) dai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky dang ha noi. chieu ke chau phu ((du hanh) or (luu hanh)) dai ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky dang ha noi. chieu ke chau phu ((du hanh) or (luu hanh)) dai ((cua tre) OR (cua te))*.
