• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (lieu tinh)) - thanh ((trung va) OR (truong va)) thong cong san toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (lieu tinh)) - thanh ((trung va) OR (truong va)) thong cong san toan tap*".
