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