• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((dang xa) OR (dang xay)) hoi. lieu ((va cam) or (va dao)) loc va hanh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((dang xa) OR (dang xay)) hoi. lieu ((va cam) OR (va dao)) loc va hanh va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((dang xa) OR (dang xay)) hoi. lieu ((va cam) or (va dao)) loc va hanh va cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((dang xa) OR (dang xay)) hoi. lieu ((va cam) or (va dao)) loc va hanh va cua tre*.
