• If you are trying to use Boolean operators, they must be ALL CAPS: te bai ((ky lang) OR (ky dang)) xa hoi. hieu va cham cuu va danh ((tai cua) OR (tai cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bai ((ky lang) OR (ky dang)) xa hoi. hieu va cham cuu va danh ((tai cua) or (tai cuc)) tre".
