从elasticsearch中的多个嵌套级别字段中搜索

Question

我想从多个嵌套级别字段中搜索。查询如。

select * from product where brand='brand1' and category='category1'.

在elasticsearch中我有两个嵌套级别映射一个是类别，另一个是品牌。

如果我写了只有品牌或类别，会返回完美的结果，但是如何在以下查询中写两个？

    $params = [
                'index' => 'my_index',
                'type' => 'product',
                'body' =>  [
                "query"=>[
                   "filtered"=>[
                      "filter"=>[
                         "bool"=>[
                            "must"=>[
                               "bool"=>[
                                  "must"=>[
                                     [
                                        "query"=>[
                                           "match"=>[
                                              "brand"=>[
                                                 "query"=>"brand1",
                                                 "type"=>"phrase"
                                              ]
                                           ]
                                        ]
                                     ],
                                     [
                                        "query"=>[
                                           "match"=>[
                                              "category"=>[
                                                 "query"=>"category1",
                                                 "type"=>"phrase"
                                              ]
                                           ]
                                        ]
                                     ]
                                  ]
                               ]
                            ]
                         ]
                      ]
                   ]
                ]
            ]      

       ];
