• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly lang xa hoi. hieu ((va nhan) OR (van nhan)) luc va hanh ((di cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly lang xa hoi. hieu ((va nhan) OR (van nhan)) luc va hanh ((di cua) or (dai cua)) te".
