• Performing a fuzzy search may retrieve terms with similar spellings: thuoc ((sach ky) OR (sac ky)) bang cac thoi. hieu ((ve cam) or (vien cac)) luc va danh di cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach ky) OR (sac ky)) bang cac thoi. hieu ((ve cam) OR (vien cac)) luc va danh di cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ky) OR (sac ky)) bang cac thoi. hieu ((ve cam) or (vien cac)) luc va danh di cua tu*".
