Description

Hierarchical Facets for Solr. In order to correctly display a taxonomy as a hierarchical facet you need to configure the requisite Twigkit service to retrieve the data structure [configured in your Solr index][1]. First you need to create a service configuration: 
 /conf
     /services
         /hierarchical
             /hierarchical.conf
The file ‘hierarchical.conf’ should be configured similar to the following example: 
name: twigkit.search.solr.service.facet.GreedySolrHierarchicalFacetService
platform: platforms.solr
parents-suffix: _parent
platform This specifies the configured platform where the taxonomy has been indexed.
parents-suffix The suffix, that if appended to the facet’s fieldname will designate the field containing parent node data. Will depend on how the taxonomy data has been indexed.
Example: 
<search:platform var="platformHierarchical" conf="services.hierarchical"></search:platform>
<search:facet facet-name="location" show="6" show-more="6">
    <facet:hierarchical facet-name="location" platform="platformHierarchical" query="query"></facet:hierarchical>
</search:facet>

​
Usage

as element: 
<facet:hierarchical
       query="{string}"
       [facet-name="{string}"]
       [platform="{string}"]
       [count-number="{string}"]
       [select="{string}"]
       [max-characters="{Number}"]
       [expand-root="{boolean}"]>
</facet:hierarchical>
