• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky lang xa hoi. hieu van cam tu ((ta thanh) OR (va thanh)) ((hai cua) OR (hoi cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky lang xa hoi. hieu van cam tu ((ta thanh) OR (va thanh)) ((hai cua) or (hoi cua)) tre".
