• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach 2)) nang xa hoi. hieu va cham soc va dinh hoi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach 2)) nang xa hoi. hieu va cham soc va dinh hoi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach 2)) nang xa hoi. hieu va cham soc va dinh hoi ((cua tre) OR (cua te))*.
