• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach kem) OR (hanh kem))) OR (cac ky)) nang xa hoi. thi van nhan tuc va hanh te cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach kem) OR (hanh kem))) or (cac ky)) nang xa hoi. thi van nhan tuc va hanh te cua tre*".
