Full-Text Index Dialog Box (Visual Database Tools)

This dialog box allows you to create a full-text index, for full-text searches on text-based columns in your database tables. A full-text index relies on a regular index, so you must create that first. The regular index must be created on a single, non-null column; it is best to choose a column with small values rather than a column with large ones. For more information, see How to: Create Indexes (Visual Database Tools).

Note

To create a full-text index, you must first create a full-text catalog for the database using an outside tool, such as SQL Server Management Studio or Enterprise Manager.

Note

Full-text index functionality is not available in Microsoft SQL Server Express.

Options

  • Selected Full-Text Index
    Lists existing full-text indexes. Select an index to show its properties in the grid to the right. If the list is empty, no full-text relationships have been defined for the table.

  • Add
    Create a new full-text index.

  • Delete
    Delete the full-text index selected in the Selected Full-Text Index list.

  • Full-Text Catalog Name
    Displays the name of the full-text catalog on which this full-text index is stored. To store the index on a different catalog, click the catalog name and choose another from the drop-down list.

    Note

    The catalog must be created first in an outside tool, such as SQL Server Management Studio or Enterprise Manager.
