• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) dang xay hoi. thien van ((nam xuc) OR (cam xuc)) va dinh ke cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) dang xay hoi. thien van ((nam xuc) OR (cam xuc)) va dinh ke cau treo".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) dang xay hoi. thien van ((nam xuc) OR (cam xuc)) va dinh ke cau treo*.
