• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang xa hoi. hieu van cam lo va thanh va ((cua te) OR (((cua tuc) OR (cua tu)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang xa hoi. hieu van cam lo va thanh va ((cua te) or (((cua tuc) OR (cua tu))))".
