• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((ang xa) OR (dang xay)) hoi. ((lieu va) OR (hieu qua)) cam duc va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((ang xa) OR (dang xay)) hoi. ((lieu va) or (hieu qua)) cam duc va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((ang xa) OR (dang xay)) hoi. ((lieu va) or (hieu qua)) cam duc va danh vi cua tre*.
