• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (chieu sang)) - ((hanh mang) OR (hanh trang)) cua thong cong thanh han tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) or (chieu sang)) - ((hanh mang) OR (hanh trang)) cua thong cong thanh han tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (chieu sang)) - ((hanh mang) OR (hanh trang)) cua thong cong thanh han tap*.
