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