• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho lieu) OR (so lieu)) tinh - thanh ((trung cap) OR (trung tuan)) khong cang dan chan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) OR (so lieu)) tinh - thanh ((trung cap) or (trung tuan)) khong cang dan chan cau*".
