• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu sach)) ky nang xa hoi. ((hieu ve) OR (hieu van)) cao suc va nhan vien cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) or (thu sach)) ky nang xa hoi. ((hieu ve) OR (hieu van)) cao suc va nhan vien cua te*".
