• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thieu ((mang xa) OR (nang x)) hoi. lieu ((va cam) OR (va cham)) duc tan hanh lam cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thieu ((mang xa) or (nang x)) hoi. lieu ((va cam) OR (va cham)) duc tan hanh lam cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach thieu ((mang xa) or (nang x)) hoi. lieu ((va cam) OR (va cham)) duc tan hanh lam cua tre*.
