• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. ((thien van) OR (thi van)) nam ((qua van) OR (quan van)) thanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. ((thien van) or (thi van)) nam ((qua van) OR (quan van)) thanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. ((thien van) or (thi van)) nam ((qua van) OR (quan van)) thanh di cua tre*.
