• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thieu lang) OR (hieu lang)) xa hoi. thi lan cam ((xuc va) OR (thuc va)) hanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thieu lang) OR (hieu lang)) xa hoi. thi lan cam ((xuc va) or (thuc va)) hanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((thieu lang) OR (hieu lang)) xa hoi. thi lan cam ((xuc va) or (thuc va)) hanh tai cua tre*.
