ES配置词库后不生效的解决方法

问题描述

我们自定义拓展词库更改后，原先的索引文档中的数据，由于不是新插入的数据，所以其倒排索引列表还是原先的分词列表数据，导致就算拓展了词库，新增的分词也没有生效。在不重新导入数据的前提下，处理办法如下

处理办法

通过_update_by_query去更新匹配的文档，如果没有指定查询，那么就会在每个文档上执行更新

POST /cloud mall-order/_update_by_query?conflicts=proceed

conflicts：

表示如果更新过程中发生异常冲突时如何处理：

（1）abort：中止（默认）

（2）proceed：继续执行
