• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ly ((nang xa) OR (nang x)) hoi. hieu ve cham luc van quan van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ly ((nang xa) or (nang x)) hoi. hieu ve cham luc van quan van cua tre*".
