ElasticSearch - 如何从聚合中排除过滤器？

Question

我用3个过滤器过滤了查询:"query": "iphone", color:5, category:10, brand:25.

我怎样才能获得其中有各个品牌的产品数量color:5和category:10？

在Solr我做到了:

fq={!tag=tag_facet_brand}facet_brand:"564"&facet.field={!ex=tag_facet_brand}facet_brand

如何从聚合上下文中排除1个过滤器？(我不能使用全局,因为我松了query:iphone,我不能使用post_filter - 因为性能).

我们刚刚离开SOLR,我们面临同样的问题.

您可以尝试全局存储桶,然后为每个存储桶添加查询过滤器:

"filter" : {
            "query" : {
                "query_string" : {
                    "query" : "iPhone"
                }
            }
        }

你应该结束这样的事情:

{
    "size": 10,
    "query": {
        "query_string": {
            "query": "iphone"
        }
    },
    "filter": {
        "bool": {
            "must": [
                {
                    "term": {
                        "brand": "564"
                    }
                },
                {
                    "term": {
                        "color": "5"
                    }
                },
                {
                    "term": {
                        "category": "10"
                    }
                }
            ]
        }
    },
    "aggs": {
        "all": {
            "global": {},
            "aggs": {
                "keyword": {
                    "filter": {
                        "bool": {
                            "must": [
                                {
                                    "query": {
                                        "query_string": {
                                            "query": "iphone"
                                        }
                                    }
                                },
                                {
                                    "term": {
                                        "color": "5"
                                    }
                                },
                                {
                                    "term": {
                                        "category": "10"
                                    }
                                }
                            ]
                        }
                    },
                    "aggs": {
                        "brand": {
                            "terms": {
                                "field": "brand"
                            }
                        }
                    }
                }
            }
        }
    }
