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