我目前有一个在产品中具有嵌套数据类型的数据集，这些数据集都列在不同的供应商中。我有各种查询来检查嵌套产品数组中的搜索条件，理想情况下，我希望能够组合所有内部命中，以便我可以对分数排名和价格等内容进行排序。目前，搜索结果以每个文档为基础返回。是否可以在弹性搜索中组合内部命中，以便我只获得所有匹配产品的列表？
示例查询
{
"_source": {
"includes": [ "*" ],
"excludes": [ "products" ]
},
"query": {
"nested": {
"path": "products",
"inner_hits": {
"size": 10,
"_source": [
"title"
]
},
"query": {
"bool": {
"must": [
{
"match": {
"products.title" : {
"query": "Dress",
"fuzziness" : 0
}
}
}
]
}
}
}
}
}

没关系，我应该更好地关注弹性搜索文档，其中指出：
搜索请求返回整个文档，而不仅仅是匹配 嵌套文件。虽然有计划支持返回 与根文档匹配的最佳匹配嵌套文档，这是 尚不支持。
我认为亲子关系可能是解决这个问题的方法。
