Elasticsearch：如何防止我的客户端自动插入顶级查询属性 [英] Elasticsearch: how to prevent my client from automatically inserting the top-level query property

问题描述

我需要生成一个具有以下结构的查询字符串：

  {
query：{
filtered：{
query：{
match_all：{} 
}，
filter：{
 .... 
} 
} 
}，
聚合：{
facets：{
terms：{
 ：subject
} 
} 
} 
} 
  

我正在使用以下客户端进行搜索：

 客户端客户端=新的TransportClient（my_settings_object）
 .addTransportAddress （新的InetSocketTransportAddress（localhost，9200））; 
 SearchResponse sr = client.prepareSearch（my_index）
 .setTypes（my_doctype）
 .setQuery（query）; //这是上面手动构建的查询字符串
 .execute（）。actionGet（）; 
 return sr; 
  

我收到以下错误：

  QueryParsingException [[my_idex]没有注册[查询]的查询] 
  

似乎这个错误在这个SO文章中解释：

elasticsearch - 没有查询[query]]

基本上，我的客户端自动将顶级查询属性插入到使它看起来像：

  {
查询：{
查询：{
 过滤：{
查询：{
match_all：{} 
}，
过滤器：{
 .... 
 
} 
}，
聚合：{
facets：{
terms：{
field：subject 
} 
} 
} 
} 
}

解决方案

使您的查询和聚合查询单个JSON对象。将查询更改为：

  {
已过滤：{
查询：{
match_all：{
 
} 
}，
过滤器：{
 .... 
} 
} 
} 
  

并更改聚合，以便它们位于单个JSON对象中：

  {
facets：{
terms：{
field：subject 
} 
} 
} 
  

设置查询和聚合SearchRequestBuilder：

  SearchResponse sr = client.prepareSearch（my_index）
 .setTypes（my_doctype）
 .setQuery（query）; //这是上面手动构建的查询字符串
 .setAggregations（aggregations.getBytes（））; 
 .execute（）。actionGet（）; 
  

I need to generate a query string with the following structure:

{
  "query": {
    "filtered": {
      "query": {
        "match_all": {}
      },
      "filter": {
       ....
      }
    }
  },
  "aggregations": {
    "facets": {
      "terms": {
        "field": "subject"
      }
    }
  }
}

I am using the following client for search:

Client client = new TransportClient(my_settings_object)
        .addTransportAddress(new InetSocketTransportAddress("localhost", "9200"));
SearchResponse sr = client.prepareSearch("my_index")
        .setTypes("my_doctype")
        .setQuery(query) ; // this is above query string built manually
        .execute().actionGet();         
return sr;

I got the following error:

QueryParsingException[[my_idex] No query registered for [query]]

It seems that this error is explained in this SO post:

elasticsearch - No query registered for [query]]

Basically, my client automatically inserts the top-level query property to make it look like:

{
    query:  {
      "query": {
        "filtered": {
          "query": {
            "match_all": {}
          },
          "filter": {
           ....
          }
        }
      },
      "aggregations": {
        "facets": {
          "terms": {
            "field": "subject"
          }
        }
      }
    }
}

How can I prevent my client from automatically inserting the top-level query property?

Thanks and regards.

解决方案

Make your query and aggregations query individaul JSON objects. Change the query to:

{
    "filtered": {
        "query": {
            "match_all": {

            }
        },
        "filter": {
            ....
        }
    }
}

And change the aggregations so that they are in individual JSON object:

    {
        "facets": {
            "terms": {
                "field": "subject"
            }
        }
    }

Set the query and aggregations in the SearchRequestBuilder:

SearchResponse sr = client.prepareSearch("my_index")
    .setTypes("my_doctype")
    .setQuery(query) ; // this is above query string built manually
    .setAggregations(aggregations.getBytes());
    .execute().actionGet();
