• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang xa hoi. lieu va ((chai cuc) OR (hai cuc)) va ((thanh le) OR (thinh le)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang xa hoi. lieu va ((chai cuc) OR (hai cuc)) va ((thanh le) or (thinh le)) cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang xa hoi. lieu va ((chai cuc) OR (hai cuc)) va ((thanh le) or (thinh le)) cua tre*.
