Hey,

I was wondering if it's possible to generate hierarchical facets directly  
in elastic search.

For example, lets say I have products and each product can be assigned  
multiple categories where categories are hierarchical is it possible to  
store this hierarchy in elasticsearch and when generating the categories  
facet for your product search results have it returned in hierarchical  
format?

Hierarchical facets are not supported in Elasticsearch:
