-  * One helpful way to understand facets is to submit queries to Solr to return faceted results directly in XML: See http://wiki.apache.org/solr/SimpleFacetParameters and scroll all the way down for examples of URLs. You can also turn on debug mode in [[:config.ini]] to see exactly which URLs VuFind is generating for its own queries.+  * One helpful way to understand facets is to submit queries to Solr to return faceted results directly in XML: See http://wiki.apache.org/solr/SimpleFacetParameters and scroll all the way down for examples of URLs.

 +===== Hierarchical Facets =====
 +
 +VuFind supports hierarchical facets with Solr. The facet values need to be indexed as described in the [[https://wiki.apache.org/solr/HierarchicalFaceting#Terms_Containing_Another_Term_in_the_Beginning|Solr wiki]] with each value always ending in a trailing slash. Hierarchical facets are defined in facets.ini (see the SpecialFacets section) and there are also settings that define how they are sorted and displayed. 
 +
 +Below is an example of how a building facet could be indexed when the record belongs to a couple of different libraries:
 +
 +  0/MainLib/
 +  1/MainLib/Adults/
 +  1/MainLib/Reference/
 +  0/BranchLib/
 +  1/BranchLib/Main/
 +
 +Below is an example of format could be indexed for a record that contains physical copies as well as an online version:
 +
 +  0/Book/
 +  1/Book/Book/
 +  1/Book/eBook/
 +
