• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang van hoi. hieu va ((cac luc) OR (coc luc)) van ((hanh em) OR (hanh kem)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang van hoi. hieu va ((cac luc) or (coc luc)) van ((hanh em) OR (hanh kem)) cua tre*".
