To include a grouping control with a result list, you must do the following:
1. Establish the desired metadata columns as managed properties in SharePoint (see “Establishing Custom Properties in SharePoint”).
2. Configure the relevant managed properties as grouping properties for Ontolica (see “The Grouping Properties Page”).
3. For each relevant result page, place an Ontolica Search Summary Web Part that is configured with grouping enabled and with an XSLT template designed to implement a grouping control. See “Ontolica Search Summary Web Part” for details about how to make these settings.
