• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) ((lang ha) or (dang xay)) hoi. hieu van cam luc va hanh lam cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) ((lang ha) OR (dang xay)) hoi. hieu van cam luc va hanh lam cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) ((lang ha) or (dang xay)) hoi. hieu van cam luc va hanh lam cua te*".
