• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky hoang van hoi. hieu ve coc luc va danh de ((((cua tre) OR (cua triet))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky hoang van hoi. hieu ve coc luc va danh de ((((cua tre) OR (cua triet))) or (cuu tre))".
