内部命中不适用于嵌套过滤器? [英] Inner hits not working with nested filter?

问题描述

我刚刚升级到 Elastic Search 1.5.0，到目前为止我无法制作 inner_hits 使用嵌套过滤器，尽管它适用于嵌套查询.

I've just upgraded to Elastic Search 1.5.0 and so far I can't make inner_hits work with a nested filter, although it works fine with a nested query.

假设我想检索 movie 对象中的内部嵌套对象 actors.

Let's say I want to retrieve the inner nested object actors within a movie object.

当我运行以下嵌套查询时:

语法 1

GET my_index/movie/_search
{
  "query": {
    "filtered": {
      "query": {"match_all": {}},
      "filter": {
        "nested": {
          "path": "actors",
          "query": {
            "match": {
              "actors.id": 12345
            }
          }, 
          "inner_hits" : {}
        }
      }
    }
  }
}

=> 我得到了记录在案的 inner_hits 这里，这很好.

=> I get the inner_hits as documented here, which is just fine.

但是当我尝试使用嵌套过滤器进行等效查询时:

But when I try doing the equivalent query with a nested filter :

语法 2

GET my_index/movie/_search
{
  "query": {
    "filtered": {
      "query": {"match_all": {}},
      "filter": {
        "nested": {
          "path": "actors",
          "filter": {
            "term": {
              "actors.id": 12345
            }
          }, 
          "inner_hits" : {}
        }
      }
    }
  }
}

=> 我收到以下解析错误

=> I get the following parse error

QueryParsingException[[my_index] [nested] 需要 'query' 或'过滤器'字段]

QueryParsingException[[my_index] [nested] requires either 'query' or 'filter' field]

(当我删除 inner_hits 时，这最后一个查询工作正常 - 当然，除了我没有得到内部命中...)

(and this last query works fine when I remove inner_hits - except of course that I don't get the inner hits ...)

我使用的语法是否有问题，或者嵌套过滤器尚未实现inner_hits?

Is there something wrong in the syntax I use or is the inner_hits not implemented yet with nested filter ?

它使用 @mdewit(谢谢！)

语法 3

GET my_index/movie/_search
{
    "query": {
        "nested": {
            "path": "actors",
            "query": {
                "filtered": {
                    "filter": {
                        "term": {"actors.id": 12345}
                    }
                }
            },
            "inner_hits" : {}
        }
    }
}

即使此语法与 嵌套过滤器文档

=> 我仍然不明白语法 2 有什么问题.对我来说这似乎是一个 ES 错误.

=> I still do not understand what is wrong with Syntax 2. It seems like an ES bug to me.

Edit 04-22-2015 : bug fixed in ES 1.5.1, see my comment below

推荐答案

在 ElasticSearch 1.5.1 中修复了错误，如所述 这里

Bug fixed in ElasticSearch 1.5.1 as stated here

所以这个语法有效(并且工作正常)

So this syntax works (and works fine)

GET my_index/movie/_search
{
  "query": {
    "filtered": {
      "query": {"match_all": {}},
      "filter": {
        "nested": {
          "path": "actors",
          "filter": {
            "term": {
              "actors.id": 12345
            }
          }, 
          "inner_hits" : {}
        }
      }
    }
  }
}

谢谢各位！
