• Performing a fuzzy search may retrieve terms with similar spellings: te ((((sach ky) OR (sac ky))) or (sach y)) sang mai hoi. hieu va cam duc va danh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sac ky))) OR (sach y)) sang mai hoi. hieu va cam duc va danh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sac ky))) or (sach y)) sang mai hoi. hieu va cam duc va danh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ky) OR (sac ky))) or (sach y)) sang mai hoi. hieu va cam duc va danh lai cua tre*.
