• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((ang xa) OR (lang xa)) hoi. hieu van ((nam duoc) OR (dat duoc)) gia thanh ha cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu ((ang xa) OR (lang xa)) hoi. hieu van ((nam duoc) or (dat duoc)) gia thanh ha cua tre".
