To use segments as a dimension, you need to create segments in the ATG Business Control Center as described in the Creating User Segments chapter of the ATG Business Control Center Administration and Development Guide. Then you need to make those segments available as options, by adding them to the Merchandising list, as follows:
While working in an Administer Commerce Search project, navigate to Segment List view of the Browse tab.
Click the Merchandising segment.
In the Details pane, update the list of segments:
Add a segment by clicking Add. When the Select an Item dialog box opens, navigate to the segment, click the check box beside it, and click OK. If you don’t see the set of segments you expected, your site administrator should make sure that the correct modules are running.
Rearrange the position of a segment in the list by changing the number beside it. To preview the new order, click Reorder. The order you provide here doesn’t affect how segments appear in other Merchandising lists.
Remove a segment from the list by clicking the Delete button beside the segment.
Click Save.
About Removing Segments
If you remove a segment from the Merchandising segment list in Search Merchandising, you make it unavailable for selection as the dimension for search configurations or search configuration folders. If you remove a segment that is already assigned to search configurations or search configuration folders, the segment remains in use only for those assets, but cannot be selected for new ones.
If, however, a segment is deleted from the ATG Business Control Center, that segment becomes unusable by all applications. Any search configuration or search configuration folder with a deleted segment can be deployed but will never be applied because, although the segment may appear in Merchandising, it won’t be visible to Search. Because there won’t be any visitor attributes associated with the resource that uses the deleted segment, that resource will never be applied.
