• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((mang cua) or (dang xay)) hoi. thi van cau ((xuc ban) OR (duc ban)) hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((mang cua) OR (dang xay)) hoi. thi van cau ((xuc ban) OR (duc ban)) hanh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((mang cua) or (dang xay)) hoi. thi van cau ((xuc ban) OR (duc ban)) hanh di cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((mang cua) or (dang xay)) hoi. thi van cau ((xuc ban) OR (duc ban)) hanh di cuu tre*.
