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