One of the possibility to avoid this would be to alter your indexing process to create this synthetic field being a concatenation, so later you could use normal cardinality aggregation, not the script one.
Of course this can go on for as many fields as you'd like. Update: For completeness, here is how the output of the above query looks. Also below is python code for generating the aggregation query and flattening the result into a list of dictionaries. {"aggregations":{"agg1":{"buckets...
The response returns the aggregation type as a prefix to the aggregation’s name. 响应将聚合类型作为聚合名称的前缀返回。 Some aggregations return a different aggregation type from the type in the request. For example, the terms, significant terms, and percentiles aggregations return different aggregat...
能用filter就不用query 增加冗余字段将部分range aggregation查询变成terms aggregation 为常用字段增加配置,将fielddata的loading设成eager,尽量多加载到内存 增加集群的缓存资源,把内存尽量多的用起来 Global ordinals Index warmer 调整aggregation的collect_mode 上SSD elasticsearch一些使用经验以及优化方法 Elasticsearch索引...

在query_string 和 multi-match 查询中,fields 越多查询越慢。你可以新增一个联合字段,在 mapping 中设置 copy_to 将多个 fields 字段自动复制到这个联合 field 字段中,这样就能把多字段查询变为单字段查询。 05 Pre-index data 预索引数据。在进行 range aggregation 范围聚合查询时,我们可以新增一个字段以在索引...

定义一个 runtime field ,值是已有两个字段的值相减,然后在这个 field 上面做 range aggregation 。 5. multi-match 要求搜索三个字段,其中一个字段权重乘2,最终得分为每个字段得分相加(也就是设置 type 为 most_fields)。 6. cross-cluster search 跨集群搜索 ...
