• If you are trying to use Boolean operators, they must be ALL CAPS: (("ngan danh thuong mai") OR ((("nganh thanh thuong mai") OR ("nhanh thanh thuong mai"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ngan danh thuong mai\") or (((\"nganh thanh thuong mai\") OR (\"nhanh thanh thuong mai\"))))~".
• Removing quotes may allow a broader search: (( ngan danh thuong mai ) or ((( nganh thanh thuong mai ) OR ( nhanh thanh thuong mai ))))~.
• Adding a wildcard symbol may retrieve word variants: (("ngan danh thuong mai") or ((("nganh thanh thuong mai") OR ("nhanh thanh thuong mai"))))*.
