• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach v nang xa hoi. lieu va ((cau luc) OR (cau phuc)) ((va danh) OR (va dinh)) di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach v nang xa hoi. lieu va ((cau luc) OR (cau phuc)) ((va danh) or (va dinh)) di cua te".
