I am stuck where I want to index Map\>\> in elastic search efficiently and build a facet/aggregation out of it.

Use case is consider the below data structure ( a general case of category and subcategory)

Data is of the form

"data" :  
{  
"name" : "foo",  
"categoryInfo":{  
"cat1": {  
subcat1,  
subcat2  
},  
"cat2" : {  
subcat3,  
subcat4,  
subcat1  
}  
}  
}
