This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The Rebuild method re-creates the Microsoft Search full-text catalog or Microsoft SQL Server index referenced by the object.
For the FullTextCatalog object, the Rebuild method removes, then re-creates the structures maintaining the full-text catalog referenced. The re-created catalog is not populated, but is ready for population. After calling the Rebuild method, use the Start method of the FullTextCatalog object to repopulate the full-text catalog.
When using the Rebuild method of an Index object referencing a clustered index, you can set the FillFactor property prior to calling the method to alter index density. For more information about index fill factor, see CREATE INDEX.
