• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) sang xa hoi. ((hieu ve) OR (hieu van)) cam luc va hanh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) sang xa hoi. ((hieu ve) or (hieu van)) cam luc va hanh lai cua tre".
