• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky ((dang xay) OR (van xay)) hoi. hieu ((van nam) or (van cau)) luc va dan lai chau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky ((dang xay) OR (van xay)) hoi. hieu ((van nam) OR (van cau)) luc va dan lai chau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky ((dang xay) OR (van xay)) hoi. hieu ((van nam) or (van cau)) luc va dan lai chau treo*".
