## elasticsearch报错：exceeds the \[index.highlight.max\_analyzed\_offset\] limit \[1000000\]. To avoid this error, set the query parameter \[max\_analyzed\_offset\] to a value less than index setting \[1000000\] and this will tolerate long field values by truncating them. ##

意思是说es从5.\*开始，不能在elasticsearch .yaml里面设置index.highlight.max\_analyzed\_offset了，需要通过配置文件或者http的PUT命令设置进去index.highlight.max\_analyzed\_offset。

解决方案，用postman或者任意一个可以post http值和参数的工具，对目标主机上部署的es进行put命令配置：

http://localhost:9200/_all/_settings?preserve_existing=true

注意，不是get或者post，而是PUT。

PUT的body请求体需要加上，内容：

{
      "index.highlight.max_analyzed_offset" : "999999999"
    }

es启动起来后，在执行http的put。

如果一切正常，es对于这个http的put返回确认结果：

{
    "acknowledged": true
    }

同时，在es的运行控制台会输出：

> updating \[index.highlight.max\_analyzed\_offset\] from \[1000000\] to \[999999999\]
