• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ((ky dang) OR (ky danh)) xay hoi. hieu ((vien cac) OR (vien dai)) duc gia thanh gia cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ((ky dang) or (ky danh)) xay hoi. hieu ((vien cac) OR (vien dai)) duc gia thanh gia cua tre*".
