• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mau hieu phap tich su dung thuoc\") OR (\"mau phieu phap tich su dung thuoc\"))~".
• Removing quotes may allow a broader search: (( mau hieu phap tich su dung thuoc ) OR ( mau phieu phap tich su dung thuoc ))~.
• Adding a wildcard symbol may retrieve word variants: (("mau hieu phap tich su dung thuoc") OR ("mau phieu phap tich su dung thuoc"))*.
