• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((van cau) OR (van dau)) tuc van doanh ((van cua) OR (ban cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((van cau) OR (van dau)) tuc van doanh ((van cua) or (ban cua)) tre*".
