Answer 1

I solved the problem,When We are using Composite

s = ProductDocument.search()
brand_name = A('terms', field='brand.name')
brand_pk = A('terms', field='brand.id')
brand_key_aggs = [
    {'brand_pk': brand_pk},
    {'brand_name': brand_name}
]
s.aggs.bucket('brand_terms', "composite", sources=brand_key_aggs) 

Example Result

 {  
               'key':{  
                  'brand_pk':869,
                  'brand_name':'Uni Baby'
               },
               'doc_count':2
            },
