lasticsearch 报错 Document contains at least one immense term 的解决方案

一、问题背景

在使用 Elasticsearch 存储较大字段数据时，出现如下异常：
ElasticsearchStatusException: Elasticsearch exception [type=illegal_argument_exception, reason=Document contains at least one immense term in field="fieldZgbpka" (whose UTF8 encoding is longer than the max length 32766)...

如下图所示：

二、错误分析

这是 Elasticsearch 的一个安全机制：默认情况下，不允许索引超大字段内容（即 term 超过 32766 bytes）。Elasticsearch 会跳过这些字段的内容，同时抛出 illegal_argument_exception。

常见触发原因：

向索引中写入了超长字符串，如大型 JSON、富文本、Base64 图片等；
默认 text 类型字段被自动建立倒排索引。

三、解决方案：

设置 index: false 禁用字段索引
如果该字段不参与搜索，仅作存储用途（比如附件内容、HTML、大文本、JSON 字符串等），可以将其设为不可索引，即：

"fieldZgbpka": {
"type": "text",
"index": false
}

四：解决步骤（我这个方案比较笨）

1.先查询有那些索引

GET wk_single_pack/_mapping

大概结果如下图：

2.删除旧索引

然后建立一个新的索引，对应的改成text 把索引禁用掉fase别的保持不变。

这是删除原有索引的命令，看到true就成功了。
DELETE /wk_single_pack

3.建立新的索引

PUT wk_single_pack
