• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sac ky)) nang ma hoi. ((thi van) or (thi hanh)) cam tuc va danh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) nang ma hoi. ((thi van) OR (thi hanh)) cam tuc va danh hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) nang ma hoi. ((thi van) or (thi hanh)) cam tuc va danh hai cau treo".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sac ky)) nang ma hoi. ((thi van) or (thi hanh)) cam tuc va danh hai cau treo*.
