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