• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky lang) OR (ky dang)) ha noi. lieu va cham coc ban ((hanh di) OR (hanh de)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky lang) OR (ky dang)) ha noi. lieu va cham coc ban ((hanh di) or (hanh de)) cua triet".
