• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang x) OR (dang xay)) hoi. thi van ((dau trung) OR (dai trung)) va xanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang x) or (dang xay)) hoi. thi van ((dau trung) OR (dai trung)) va xanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang x) or (dang xay)) hoi. thi van ((dau trung) OR (dai trung)) va xanh di cua tre*.
