我迷路了,需要你的建議。我有一個包含多級子文檔的嵌套Solr文檔。這裏是一個JSON例子,所以你可以看到完整的結構:如何從solr讀取嵌套結構?
{
"id": "Test Library",
"description": "example of nested document",
"content_type": "library",
"authors": [{
"id": "author1",
"content_type": "author",
"name": "First Author",
"books": [{
"id": "book1",
"content_type": "book",
"title": "title of book 1"
}],
"shortStories": [{
"id": "shortStory1",
"content_type": "shortStory",
"title": "title of short story 1"
}]
},
{
"id": "author2",
"content_type": "author",
"name": "Second Author",
"books": [{
"id": "book1",
"content_type": "book",
"title": "title of book 1"
}],
"shortStories": [{
"id": "shortStory1",
"content_type": "shortStory",
"title": "title of short story 1"
}]
}]
}
我想查詢的文檔和檢索嵌套結構。我嘗試使用ChildDocumentTranformerFactory但它扁平的結果是公正圖書館和所有其他文件孩子:
{
"id": "Test Library",
"description": "example of nested document",
"content_type": "library",
"_childDocuments_":[
{"id": "author1",
"content_type": "author",
"name": "First Author"
},
{"id": "book1",
"content_type": "book",
"title": "title of book 1"
},
{
"id": "shortStory1",
"content_type": "shortStory",
"title": "title of short story 1"
},
{
"id": "author2",
"content_type": "author",
"name": "Second Author"
},
{
"id": "book1",
"content_type": "book",
"title": "title of book 1"
},
{
"id": "shortStory1",
"content_type": "shortStory",
"title": "title of short story 1"
}
]
}
以下是查詢參數我用:
q={!parent which='content_type:library'}
df=id
fl=*,[child parentFilter='content_type:library' childFilter='id:*']
wt=json
indent=true
什麼是閱讀的最好方式來自Solr的嵌套結構?我需要做一些刻面嗎?
我使用Solr的版本5.2.1
你能否提供一個創建虛擬關係的例子? – jencoston
