• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky lang xa hoi. hieu van lam duoc ma doanh ((van cuu) OR (van cu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te sach)) ky lang xa hoi. hieu van lam duoc ma doanh ((van cuu) OR (van cu)) tre".
