• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky dang) OR (ky nang)) mam hoa. thien ((danh ca) OR (dan ca)) dua ban thanh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky dang) OR (ky nang)) mam hoa. thien ((danh ca) or (dan ca)) dua ban thanh hai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky dang) OR (ky nang)) mam hoa. thien ((danh ca) or (dan ca)) dua ban thanh hai cua triet*.
