Elasticsearch Filter over dynamic nested fields with aggregation

I have products with dynamic attributes (filters). I need to get dynamically counts for each value for the filter according to the search query.

I have following mapping for products index:

{  
   "products":{  
      "mappings":{  
         "properties":{  
            ...
            "dynamicFilters":{  
               "type":"nested",
               "properties":{  
                  "name":{  
                     "type":"keyword"
                  },
                  "value":{  
                     "type":"keyword"
                  }
               }
            },
            ...
         }
      }
   }
}

And following aggregation request:

'size': 0,
'query': {
    'bool': {
        'must': {
            'match': {
                'category': 'Notebooks'
            }
        },
        'filter': {
            {'nested': {
                'path': 'dynamicFilters',
                'query': {
                    'bool': {
                        'filter': {
                            {'term': {'dynamicFilters.name': 'processor'}},
                            {'terms': {'dynamicFilters.value': {'Ryzen 7'}}},
                        },
                    }
                }
            },
        }
    }
},

'aggs': {
    //'dynamicFilters': {
        //'global': {},   <-- global type commented here
        //'aggs': {
            'dynamicFilters': {
                'nested': {
                    'path': 'dynamicFilters',
                },
                'aggs': {
                    'name': {
                        'terms': {
                            'field': dynamicFilters.name',
                            'size': 20
                        },
                        'aggs': {
                            'value': {
                                'terms': {
                                    'field': 'dynamicFilters.value',
                                    'size': 20
                                }
                            }
                        }
                    },
                }
            },
        //}
    //}
},

The problem is when in the search query will be enabled filter, for instance, "proccesor" with value "Ryzen 7" - in response won't be aggregation for all "processor" values, except "Ryzen 7".

I've tried to make this work with global type, but in this case aggs stops working with search query and return all existing counts for values.

Any help will be highly appreciated, thank you!
