+ I put together that hierarchical faceting wiki page a couple of years ago when helping a customer evaluate SOLR-64 vs. SOLR-792 vs.other approaches.  Since then, SOLR-792 morphed and is committed as pivot faceting.  SOLR-64 spawned a PathTokenizer (SOLR-1057?) which is part of Solr now too.

  = Overview =
  There are many cases where documents represent objects associated with hierarchical structures.  For example, if documents represent restaurants one might want to have geographical hierarchies such as "US/California/Cupertino".  There are various indexing techniques for faceting on hierarchical structures.  At first, this wiki page is designed to describe the various approaches, comparing and contrasting them across various real-world use cases.  As approaches become codified and committed to Solr proper, this page will evolve to be a HOW-TO.
