• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((hieu nganh) OR (hiem ngan)) - thanh truong va ((nhung cong) OR (thong thong)) ban thanh van*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((hieu nganh) OR (hiem ngan)) - thanh truong va ((nhung cong) or (thong thong)) ban thanh van*".
