弹性搜索，多重匹配过滤器？ [英] ElasticSearch, multi-match with filter?

问题描述

  {
我在ES中有一个多匹配查询，并希望添加一个过滤器。 $$$
查询：这是一个测试，
fields：[subject ^ 2，message] 
} 
} 
  

添加此过滤器的语法是什么？

我试过：

  {
multi_match=> {
query=> list，
fields=> [username] 
 
}，
filter=> {
term=> {username=> slimkicker} 
} 
} 
  

解决方案

根据您的需要，您必须将过滤器置于正确的位置。您有两个选项：

使用顶级过滤器并将过滤器仅应用于搜索结果，但不适用于构面

  {
查询：{
multi_match{
查询：这是一个测试，
fields：[subject ^ 2，message] 
} 
}，
filter：{
term：{username slimkicker} 
} 
} 
  

使用过滤的查询并应用过滤器搜索结果和方面

  {
查询：{
已过滤： {
查询：{
multi_match：{
query：这是一个测试，
fields：[subject ^ 2消息] 
} 
}，
过滤器：{
term：{username：slimkicker} 
} 
} 
} 
} 
  

I have a multi-match query in ES, and wish to add a filter.

{
  "multi_match" : {
    "query" : "this is a test",
    "fields" : [ "subject^2", "message" ]
  }
}

What is the syntax for adding this filter?

I tried:

{
  "multi_match" => {
    "query" => "list",
    "fields" => [ "username" ]

  },
"filter" => {
        "term" => { "username" => "slimkicker"}
    }
}

解决方案

Depending on what you need you have to put the filter in the proper position. You have two options:

Use a top-level filter and apply the filter only to the search results but not to the facets

{
    "query" : {
        "multi_match" {
            "query" : "this is a test",
            "fields" : [ "subject^2", "message" ]
        }
    },
    "filter" : {
        "term" : {"username":"slimkicker"}
    }
} 

Use a filtered query and apply the filter to both the search results and the facets

{
    "query" :{
        "filtered" : {
            "query" : {
                "multi_match" : {
                    "query" : "this is a test",
                    "fields" : [ "subject^2", "message" ]
                }
            },
            "filter" : {
                "term" : {"username":"slimkicker"}
            }
        }
    }
}
