• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((((rang ma) OR (sang ma))) OR (tang ma)) hoi. hieu va cham duc va thanh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((((rang ma) OR (sang ma))) or (tang ma)) hoi. hieu va cham duc va thanh hai cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((((rang ma) OR (sang ma))) or (tang ma)) hoi. hieu va cham duc va thanh hai cua triet*.
