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