Hey Erick, Thanks for the response. I haven't used PathHierarchyTokenizerFactory before... Seems with this approach, I'd flatten all the categories pertaining to a product into one Solr field... I guess using the facet.prefix I wont lose the granularity I need to facet on individual categories and can maintain the hierarchy.. I'll take a look at it. Thanks!

In essence, it indexes each sub-path as a token, which makes lots of faceting tasks easier. I.e. lev1/lev2/lev3 gets tokenized as three tokens lev1/lev2/lev3 lev1/lev2 lev1 If that works, I'm not quite sure why you need dynamic fields here, but then I only skimmed.
