我查询elasticsearch嵌套字段，并在资源中只得到嵌套字段类别。这段代码适用于没有嵌套字段。

aggs: {
        categories: {
            nested: {
                path: "categories"
            },
            aggs: {
                category_name: {
                    terms: {
                        field: "categories.categoryId.keyword",
                        min_doc_count: 1,
                        size: 500,
                        order: {
                            _count: "desc"
                        },
                    },
                    aggs: {
                        product: {
                            top_hits: {
                                size: 1,
                                _source: {
                                    include: [
                                        "id", "assets", "categories"
                                    ]
                                }
                            }
                        }

                    }
                }
            }
        }
    }
