• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty xang) OR (ly hang)) xa hoi. hieu van luat duoc ma hang va ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty xang) or (ly hang)) xa hoi. hieu van luat duoc ma hang va ((cua tre) OR (cua te))".
