注释
Microsoft Search requires a single column to identify rows participating in an index that supports full-text query. The column designated must contain unique, non-null values and must participate in a table's PRIMARY KEY constraint or UNIQUE index.
Use UniqueIndexForFullText to configure Microsoft Search full-text index key column use.
