• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. ((hieu ve) OR (lieu va)) cau ((truc xa) OR (truoc xay)) hanh vai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. ((hieu ve) or (lieu va)) cau ((truc xa) OR (truoc xay)) hanh vai cua tuc".
