• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky dang xay hoi. hieu ((((ve pham) OR (vi pham))) OR (v pham)) duc va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky dang xay hoi. hieu ((((ve pham) OR (vi pham))) or (v pham)) duc va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ky dang xay hoi. hieu ((((ve pham) OR (vi pham))) or (v pham)) duc va thanh vinh cuu tre*.
