• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang xa hoi. lieu va dau ((tuc van) OR (truc van)) ((thanh vi) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty nang xa hoi. lieu va dau ((tuc van) OR (truc van)) ((thanh vi) or (hanh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang xa hoi. lieu va dau ((tuc van) OR (truc van)) ((thanh vi) or (hanh vi)) cua tre*.
