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