在 Solr 连接查询的结果中获取连接数据
Get joined data in result for Solr Join Query
我有以下 json 个文件：
[{
"entity_id":"A1",
"entity_desc":"cat",
"relation_id": "A2",
"relation_type":"kind of"
},
{
"entity id":"A2",
"entity_desc":"Animal",
"relation_id": "A9",
"relation_type":"xyz"
} ,
]
我已经用 solr 索引了它们，现在我想使用连接查询来获取结果：
cat "is kind of" Animal.
如何将文档1中的relation_id映射到文档2中的relation_id？
提前致谢
无法从两个实体获得结果。
您只能通过加入的实体来限制您的查询。
此处引自solr wiki：
Joins in Solr are not really equivalent to
SQL Joins because no information about the table being joined "from"
is carried forward into the final result.
A more appropriate SQL analogy would be an "inner query".
