• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty hang van hoe. hieu van ((nam luc) OR (nang luc)) ((va danh) OR (va dan)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty hang van hoe. hieu van ((nam luc) or (nang luc)) ((va danh) OR (va dan)) vi cua triet*".
