如何通过Elastic中的JOIN字段查找

Question

早上好，我有一个问题，请给我一个实用的代码答案。 我有两个表Orders和Locations 我想查询“纽约球”这样的查询，并希望从位置为23（纽约）的订单表中接收所有有关球的查询

我有这样的地图

$mapping = [
            'index' =>'elastic',
            'type'=>'order',
            'body'=>[
                'properties'=>[
                  'item_name' => [
                        'type' => 'text',
                        'analyzer' => "ngram_analyzer_with_filter",
                    ],
                    'order_description' => [
                        'type' => 'text',
                        'analyzer' => "ngram_analyzer_with_filter",
                    ],
                    'id' => [
                        'type' => 'text',
                        'analyzer' => "ngram_analyzer_with_filter",
                    ],
                    'notes' => [
                        'type' => 'text',
                        'analyzer' => "ngram_analyzer_with_filter",
                    ]
                ]
            ]


        ];

还有这样的查询构建器

 $items = $this->search->search([
                'index' => 'elastic',
                'type' => 'order',
                'body'=>[
                    'query'=>[
                        "multi_match"=>[
                            "fields"=>["item_name^5","location^4","order_description^3","notes^2"],
                            "query"=>$query
                        ]
                    ],
                    "highlight" => [
                        "pre_tags"  => "<b style='color:#da4f49'>",
                        "post_tags" => "</b>",
                        "fields" => [
                            "item_name" => new \stdClass(),
                            "order_description"=> new \stdClass(),
                            "id" => new \stdClass(),
                            "notes" => new \stdClass()

                        ]
                    ]]]


        );

请提供一个可以帮助我的代码，请将代码发送给我，因为我根本不理解该主题，而且我很难理解除代码以外的其他内容。感谢所有人当我尝试创建索引映射时

 "location_name"=> [
       "type"=> "join",
       "relations"=>
       ["location"=> "order" ]
 ]

我收到一个错误，没有在字段[location_id]“}]上声明类型[join]的处理程序
