Ok so we can do a facets search based on multiple string terms attached to a  
document using an array as explained here  
[http://www.elasticsearch.org/guide/reference/api/search/facets/index.html](http://www.elasticsearch.org/guide/reference/api/search/facets/index.html)  
with the tags example.

Now can we achieve the same if our field is not a string array but a more  
complex object like:

```
           "categories":{

              "type":"object",

              "properties":{

                 "name":{

                    "type" : "string",

                    "index":"not_analyzed"

                 },

                 "content" : { 

                    "type" : "string" 

                 }

              }

           }

```

In this mapping example I would like to do a facet for the categories.name  
when there would possibly be multiple categories per document in this  
structure.

Thanks,

Yannick
