• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((nang xa) OR (dang xay)) hoi. ((hieu va) OR (hieu qua)) cam xuc ban thanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((nang xa) or (dang xay)) hoi. ((hieu va) OR (hieu qua)) cam xuc ban thanh di cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty ((nang xa) or (dang xay)) hoi. ((hieu va) OR (hieu qua)) cam xuc ban thanh di cua te*.
