• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) or (sach ty)) lang van hoa. hieu ve ((cham tu) OR (cam tu)) va hanh tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) lang van hoa. hieu ve ((cham tu) OR (cam tu)) va hanh tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach ty)) lang van hoa. hieu ve ((cham tu) OR (cam tu)) va hanh tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sach ty)) lang van hoa. hieu ve ((cham tu) OR (cam tu)) va hanh tai cuu tre*.
