• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) nang xa hoi. ((hieu va) OR (hieu qua)) cam luc van tuan tue cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach y)) nang xa hoi. ((hieu va) or (hieu qua)) cam luc van tuan tue cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach y)) nang xa hoi. ((hieu va) or (hieu qua)) cam luc van tuan tue cua tre*.
