• If you are trying to use Boolean operators, they must be ALL CAPS: ho chinh sach - cang ((thanh va) OR (thong va)) ((nhung cong) OR (hang cong)) dan than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - cang ((thanh va) or (thong va)) ((nhung cong) OR (hang cong)) dan than cao".
