在Elastic Search中对数组元素进行查询字符串搜索

我正在尝试通过一个简单的示例应用程序学习Elasticsearch,该应用程序列出了与人相关的报价。映射示例如下所示:

{ 

"people" : {

"properties" : {

"name" : { "type" : "string"},

"quotations" : { "type" : "string" }

}

}

}

一些示例数据可能看起来像:

{ "name" : "Mr A",

"quotations" : [ "quotation one, this and that and these"

, "quotation two, those and that"]

}

{ "name" : "Mr B",

"quotations" : [ "quotation three, this and that"

, "quotation four, those and these"]

}

我希望能够对单个引用使用querystring api,并返回匹配的人。例如,我可能想查找报价包含(此与这些)的人-应该返回“ A先生”而不是“

B先生”,依此类推。我该如何实现?

编辑1:

安德烈(Andrei)在下面的回答似乎可行,数据值现在看起来像:

{"name":"Mr A","quotations":[{"value" : "quotation one, this and that and these"}, {"value" : "quotation two, those and that"}]}

但是,我似乎无法使query_string查询正常工作。以下没有结果:

{

"query": {

"nested": {

"path": "quotations",

"query": {

"query_string": {

"default_field": "quotations",

"query": "quotations.value:this AND these"

}

}

}

}

}

有没有办法让query_string查询与嵌套对象一起工作?

Edit2:是的,请参阅Andrei的答案。

回答:

为了达到该要求,您需要查看嵌套对象,而不是查询平整的值列表,而是查询该嵌套对象中的各个值。例如:

{

"mappings": {

"people": {

"properties": {

"name": {

"type": "string"

},

"quotations": {

"type": "nested",

"properties": {

"value": {

"type": "string"

}

}

}

}

}

}

}

值:

{"name":"Mr A","quotations":[{"value": "quotation one, this and that and these"}, {"value": "quotation two, those and that"}]}

{"name":"Mr B","quotations":[{"value": "quotation three, this and that"}, {"value": "quotation four, those and these"}]}

查询:

{

"query": {

"nested": {

"path": "quotations",

"query": {

"bool": {

"must": [

{ "match": {"quotations.value": "this"}},

{ "match": {"quotations.value": "these"}}

]

}

}

}

}

}
