对所有退信邮箱的域名进行terms聚合,email 采用keword 存储.一般情况terms 只对特定确定字段进行聚合操作。本需求需要对这个特定字段进行部分截取,然后对这个截取后得到的域名进行聚合统计。在关系型数据库中一般可以通过视图来解决。经过一定的官方文档阅读,es terms agg api居然提供了terms agg script 功能 https://www.elastic.co/guide/en/elasticsearch/reference/5.6/search-aggregations-bucket-terms-aggregation.html
#script 章节,采用painless 的语法进行脚本定制.
.value
方法,不然会报Unable to find dynamic method [substring] with [1] arguments for class [org.elasticsearch.index.fielddata.ScriptDocValues.Strings]
异常,明明 email的mapping 设置的是keyword,莫非和String不是一个东西?s
