• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach thi ((nang xa) OR (nang x)) hoi. lieu va cac luc ((bat thanh) OR (dat thanh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach thi ((nang xa) OR (nang x)) hoi. lieu va cac luc ((bat thanh) or (dat thanh)) vi cua te".
