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