ElasticSearch：没有为[match]注册过滤器

Question

我正在尝试对我的ElasticSearch Server进行此查询。

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

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

基本上，我希望检索名称中与“
network”匹配的所有产品，但仅过滤department_name与book或匹配的产品electronics。当我执行此查询时，我收到此错误信息。

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] No filter registered for [match]]，但无法理解这里出了什么问题。

Answer 1

match 是查询，而不是过滤器。

term在这种情况下，您可能需要-filter。
