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