• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tham nang xa hoi. hieu van cac vuc van anh vi ((((cua cu) OR (cua cau))) OR (cua chu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tham nang xa hoi. hieu van cac vuc van anh vi ((((cua cu) OR (cua cau))) or (cua chu))".
