• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach y ((nang xa) OR (dang xay)) hoi. thien ((van cham) OR (van tham)) xuc van minh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach y ((nang xa) or (dang xay)) hoi. thien ((van cham) OR (van tham)) xuc van minh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: bo sach y ((nang xa) or (dang xay)) hoi. thien ((van cham) OR (van tham)) xuc van minh vi cua tre*.
