• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang xa) OR (lang van)) hoi. hieu va giao duc hoang thanh ((vai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) OR (lang van)) hoi. hieu va giao duc hoang thanh ((vai cua) or (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) OR (lang van)) hoi. hieu va giao duc hoang thanh ((vai cua) or (thai cua)) tre*.
