• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang x)) hoi. hieu va cham soc ban ((hanh vinh) OR (hanh tinh)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (nang x)) hoi. hieu va cham soc ban ((hanh vinh) OR (hanh tinh)) cuu tre".
