Refinement Panel Overview
Applies to: SharePoint Server 2010
The Refinement Panel Web Part provides a summary of search results and enables users to filter results, for example, by kind of content (document, spreadsheet, presentation, Web page, and so on), content location (such as SharePoint sites), content author, or date last modified. You can also configure custom refinement categories based on managed properties and enterprise content management (ECM) taxonomy nodes.
Customizing the Refinement Panel's Filter Categories
The Refinement Panel Web Part's FilterCategoriesDefinition property contains the XML that specifies the filter categories. You can view and modify this property from the Refinement Panel Web Part tool pane in the SharePoint Server search user interface.
To modify the filter category XML for the Refinement Panel Web Part
In your browser, navigate to the results page URL:
On the Site Actions menu, click Edit Page.
In the Refinement Panel Web Part, click the edit arrow to display the Web Part menu, and then click Edit Web Part. This opens the Web Part tool pane.
In the Refinement section, clear the Use Default Configuration check box.
In the Refinement section, click the ellipsis (…) button for the Filter Category Definition field.
This opens the Text Entry window for the Refinement Web Part's FilterCategoriesDefinition property. You can modify the XML directly in this window; however, you may find it easier to copy the code to a file. You can then edit that file by using an application such as Microsoft Visual Studio 2010. After you have finished editing the file, you can copy the modified code back into the Text Entry window and save your changes to the Web Part.
