• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach y)) lang xa hoi. thien ((van tham) OR (van tuan)) tuc va dinh dau cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) or (sach y)) lang xa hoi. thien ((van tham) OR (van tuan)) tuc va dinh dau cua tre".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) or (sach y)) lang xa hoi. thien ((van tham) OR (van tuan)) tuc va dinh dau cua tre*.
