This step-by-step article describes how to configure a Web site for indexing in Windows 2000.

Windows 2000 Indexing Service creates an index of document content and properties (such as file name, date created, date modified, author name, and number of characters) that can be searched quickly and easily. Index information is stored in catalogs.

If you install Indexing Service on the Web server, a default Web catalog is created in the Inetpub folder. This catalog contains an index of the default Web site. You can add and remove additional catalogs or configure existing catalogs to meet your requirements at any time. For example, you may want to create a catalog for each Web site that you want to index.

Use the Indexing Service snap-in to create catalogs and administer Indexing Service. After you create a new catalog, you must associate a Web site with the catalog, and then use the Internet Information Services (IIS) snap-in to configure the Web resources that you want to use for indexing. When you enable indexing for a Web resource, the content is included in the catalog and users can perform searches (usually by using a query form on a Web page) on that resource.

You can enable indexing at either the server, Web site, or folder level. Server level settings apply to indexable content on all Web sites on the server, site level settings apply to all indexable content within that site, and folder level settings apply to all indexable content within that folder and subfolders.

To create a catalog and configure a Web site for indexing:

1. Create a new catalog.
2. Associate a Web site with the catalog.
3. Configure Web resources for indexing.
4. Restart Indexing Service.

The following sections describe how to complete these tasks.
