You can create with commands:
A. Creating unique indexes, full-text catalogs, and full-text indexes
The following example is in the ADVENTUREWORKS2012 sample databasethe Jobcandidateid column of the Humanresources.jobcandidate table creates a full-text index. The example then creates a default full-text catalog, ft. Finally, the example uses the ft directory and system Stoplist to create a full-text index on the Resume column.
Copy
Use AdventureWorks2012; Gocreate UNIQUE INDEX Ui_ukjobcand on Humanresources.jobcandidate (Jobcandidateid); CREATE fulltext CATALOG ft as DEFAULT; CREATE Fulltext Index on humanresources.jobcandidate (Resume) KEY index Ui_ukjobcand with stoplist = SYSTEM; GO
Workaround for SQL Server Management Studio Express does not support updating full-text Catalogs
