• If you are trying to use Boolean operators, they must be ALL CAPS: hoc kinh sach - anh ((((quan tran) OR (quang tran))) OR (xuan tran)) phung cong tap doan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc kinh sach - anh ((((quan tran) OR (quang tran))) or (xuan tran)) phung cong tap doan cau*".
