• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) OR (nang x)) hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang xa) OR (nang x)) hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vi cuu tre*.
