• Performing a fuzzy search may retrieve terms with similar spellings: te sach y lang xa hoi. hieu van lam ((tuc van) or (thuc dan)) hanh di ((cua tu) OR (cua cu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu van lam ((tuc van) OR (thuc dan)) hanh di ((cua tu) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu van lam ((tuc van) or (thuc dan)) hanh di ((cua tu) OR (cua cu))".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu van lam ((tuc van) or (thuc dan)) hanh di ((cua tu) OR (cua cu))*.
