solr嵌套文档：对父母文档的查询，该文档具有多个特定的嵌套文档
让我们想象我有几个嵌套文档的文档：
{
"id": "doc1",
"type": "maindoc",
"title": "some document 1 title"
"nested": [
{
"id": "nested1",
"nested_type": "nestedType1",
"title": "nested doc 1 title"
},
{
"id": "nested2",
"nested_type": "nestedType2",
"title": "nested doc 2 title"
},
{
"id": "nested3",
"nested_type": "nestedType3",
"title": "nested doc 3 title"
}
]
}
因此，如果我想搜索已嵌套文档1的文档 - 我要这样做：
{!parent which='type:maindoc'}
nested_type:nestedType1
但是，如果我想搜索同时有2个特定孩子的文档，该怎么办？ 例如，我想找到具有NestedType1 + NestedType2的DOC。
显然，这样的查询将不起作用：
{!parent which='type:maindoc'}
nested_type:nestedType1 AND nested_type:nestedType2
那我该怎么做？这根本可能吗？
Let's imagine I have document with several nested documents:
{
"id": "doc1",
"type": "maindoc",
"title": "some document 1 title"
"nested": [
{
"id": "nested1",
"nested_type": "nestedType1",
"title": "nested doc 1 title"
},
{
"id": "nested2",
"nested_type": "nestedType2",
"title": "nested doc 2 title"
},
{
"id": "nested3",
"nested_type": "nestedType3",
"title": "nested doc 3 title"
}
]
}
So now if I want to search for document which has nested doc 1 - I do this:
{!parent which='type:maindoc'}
nested_type:nestedType1
But what if I want to search for document which has 2 specific children at the same time?
For example I want to find doc which has both nestedType1 + nestedType2.
Obviously query like this will not work:
{!parent which='type:maindoc'}
nested_type:nestedType1 AND nested_type:nestedType2
So how can I do that? Is that possible at all?

像这样的事情在我的测试中做到了一个技巧：
（{！parent wher ='type：maindoc'v ='nested_type：nestedType1'}）和（{！parent wher ='type：maindoc'v ='nested_type： NestedType2'}）Something like this did the trick in my testing:
({!parent which='type:maindoc' v='nested_type:nestedType1'}) AND ({!parent which='type:maindoc' v='nested_type:nestedType2'})
