A search configuration tree can have only one asset at the root. Unless your environment uses a single search configuration, that root asset must be a search configuration folder that holds other search configuration folders and/or search configurations.
To create a top-level search configuration folder:
In a Search Merchandising project, display the Search Configuration Tree and click the Project tab.
Click the Create New button and then click Search Configuration Folder in the .
In the Name text box, enter a descriptive a name for the folder. Choosing a name that represents the dimension associated with the folder helps distinguish it from others.
If this is not the top-level search configuration folder (which would also be the first search configuration folder you create), you can see a drop-down list named for the type of dimension held by this folder: Segment, Language, or Site. Select the appropriate dimension. The option All Others indicates that the search configurations in the search configuration folder are used only when a site visitor’s language isn’t represented by an existing search configuration or search configuration folder.
Note: If you don’t see an option in the list, it may be in use by another resource; a dimension value can be used just once in a given level. Additional languages and segments may be added by your site administrator.
From the Contents Vary By drop-down list, select a dimension type. All items contained by this search configuration folder will need to provide unique values for the dimension type you select. Only one dimension type appears in the list if the folder you are creating is not the root folder.
Click the Create button.
The search configuration folder appears in the Navigation pane tree.
