• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) or (sach tu)) dang ca phoi. hieu va cam xuc ((va sanh) OR (va danh)) dan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach tu)) dang ca phoi. hieu va cam xuc ((va sanh) OR (va danh)) dan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach tu)) dang ca phoi. hieu va cam xuc ((va sanh) OR (va danh)) dan cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach tu)) dang ca phoi. hieu va cam xuc ((va sanh) OR (va danh)) dan cua tre*.
