注释
If TRUE, the referenced index is used by Microsoft Search for row identification.
If FALSE, the referenced index is not used by Microsoft Search.
Microsoft Search requires that a single column identify rows participating in an index supporting full-text query. The column designated must contain unique, nonnull values and must participate in a PRIMARY KEY or UNIQUE key constraint. A table that contains a PRIMARY KEY constraint does not require a separate unique index for Microsoft Search configuration.
Use UniqueIndexForFullText to configure Microsoft Search full-text index key column use.
