• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu ha nam thu va danh sai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sach kem))) OR (sach ty)) nang ma hoa. hieu ha nam thu va danh sai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu ha nam thu va danh sai cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu ha nam thu va danh sai cua tre*.
