• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu sach)) ky nang xa hoi. hieu ((ve cao) OR (ve cac)) suc va nhan tien 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 cao) or (ve cac)) suc va nhan tien cua te".
