• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ty nang xa hoi. thi ((van hac) OR (van ha)) tuc va thanh lap cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ty nang xa hoi. thi ((van hac) OR (van ha)) tuc va thanh lap cua triet*".
