如何在 ES 6.0 中对示例执行 has_child 查询
How perform has_child query for examples in ES 6.0
Here 是 elasticsearch 中关于 join
类型的例子。我有插入映射,parents 和 children:
PUT my_index
{
"mappings": {
"doc": {
"properties": {
"my_join_field": {
"type": "join",
"relations": {
"question": "answer"
}
}
}
}
}
}
PUT my_index/doc/1?refresh
{
"text": "This is a question",
"my_join_field": {
"name": "question"
}
}
PUT my_index/doc/2?refresh
{
"text": "This is a another question",
"my_join_field": {
"name": "question"
}
}
PUT my_index/doc/1?refresh
{
"text": "This is a question",
"my_join_field": "question"
}
PUT my_index/doc/2?refresh
{
"text": "This is another question",
"my_join_field": "question"
}
现在我正在尝试通过 children:
搜索 parents
GET /my_index/doc/_search
{
"query": {
"has_child": {
"type": "my_join_field",
"query": {
"match" : {
"text": "question"
}
},
"ignore_unmapped": true
}
},
"highlight" : {
"fields" : {
"content" : {}
}
}
}
我没有得到任何结果。 :( >:(
首先 type
字段应该是什么???他们被告知 types 已被删除
其次,我必须添加ignore_unmapped
(看起来here)但仍然没有结果
那么在elasticsearch例子中如何通过has_child
查询数据找到parent?
查看11_parent_child.yml 文件。它包含父项、子项的索引并对子项执行查询。它是 yaml
,但我认为转换为 json
是显而易见的。
