ElasticSearch:没有为 [match]] 注册过滤器 [英] ElasticSearch: No filter registered for [match]]

问题描述

我正在尝试对我的 ElasticSearch 服务器执行此查询.

I'm trying to do this query to my ElasticSearch Server.

{
    "query" : {
        "match" : {
            "name" : "network"
        }
    },
    "facets" : {
        "departments" : { 
            "terms" : {
                "field" : "department_name"
            } 
        }
    },

    "filter" : {
        "bool": {
            "should": [
                { "match" : {"department_name" : "book"}},
                { "match" : {"department_name" : "electronics"}}]            
        }   
    }
}

基本上，我希望检索其名称中与network"匹配的所有产品，但仅过滤那些与 department_name 匹配的 book 或 electronics.当我执行此查询时，我收到此错误消息.

Basically, I wish to retrieve all the products that match "network" in its name, but filtering only to those which department_name matches either book or electronics. When I perform this query, I receive this error message.

curl -X POST "http://localhost:9200/products/_search?pretty=true" -d '{
    "query" : {
        "match" : {
            "name" : "network"
        }
    },
    "facets" : {
        "departments" : { 
            "terms" : {
                "field" : "department_name"
            } 
        }
    },

    "filter" : {
        "bool": {
            "should": [
                { "match" : {"department_name" : "book"}},
                { "match" : {"department_name" : "electronics"}}]            
        }   
    }
}

我想这里的关键是 QueryParsingException[[products] 没有为 [match]] 注册过滤器，但不明白这里出了什么问题.

I suppose the key here is QueryParsingException[[products] No filter registered for [match]], but cannot understand what's wrong here.

推荐答案

match 是一个查询，而不是一个过滤器.

match is a query, not a filter.

在这种情况下，您可能需要 term-filter.

You probably want the term-filter in this case.
