• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach ty)) nang ma hoi. lieu va cam luc va tinh ((da va) OR (do va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) OR (sach ty)) nang ma hoi. lieu va cam luc va tinh ((da va) or (do va)) triet".
