On the Index tab of a forum index, you can define which documents on the site will be indexed. This is done by defining allowed and excluded forums.
The dialogs for defining new allowed/excluded content can be accessed using the Add allowed forums () and Add excluded forums () links.
Adding allowed forums
1. Click the Add allowed forums () link.
2. In the following dialog, first use the Site name drop-down to choose the site whose forums will be indexed. If you select (all), all forums on all sites in the system will be indexed.
3. If you selected a particular site in the previous step, click the Select button next to the Forums field. The dialog depicted in the screenshot below will be displayed.
Use the Forum group drop-down to select a forum group. Its child forums will be listed below. To include a forum in the index, enable () the appropriate check-boxes. Click OK to save the settings.
Adding excluded forums
Excluded forums make sense only when you have all forums defined as allowed. By defining a forum as excluded, it will not be indexed and all forums but the excluded one will be indexed.
You can define an excluded forum using the Add excluded forums () link, while the procedure is the same as when adding allowed forums.
