• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) dang xa hoi. lieu va cam ((xuc ban) OR (duc van)) danh thai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sac ky)) dang xa hoi. lieu va cam ((xuc ban) or (duc van)) danh thai cua tre".
