• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cac pha ve gioi bon thuong tin ) OR ( su sach nha ma nguoi ((co thong) OR (co phong)) tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cac pha ve gioi bon thuong tin ) or ( su sach nha ma nguoi ((co thong) OR (co phong)) tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu cac pha ve gioi bon thuong tin ) or ( su sach nha ma nguoi ((co thong) OR (co phong)) tin ))*.
