• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang xa hoi. hieu vu cham hoc va ((((danh hoi) OR (dang khoi))) OR (danh hoc)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. hieu vu cham hoc va ((((danh hoi) OR (dang khoi))) or (danh hoc)) cua te".
