• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((hanh trang) OR (hanh trinh)) ((((thuc sach) OR (thuat sach))) OR (thuc cach)) nha pho thong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((hanh trang) or (hanh trinh)) ((((thuc sach) OR (thuat sach))) or (thuc cach)) nha pho thong".
