【问题描述】：
我正在尝试禁用 Elastic Search 索引的动态映射器。下面是我通过 Kibana 控制台运行的一系列查询以对其进行测试。
我认为添加 'index.mapper.dynamic' 应该在索引级别禁用它，对吗？
在这里编辑：
我还尝试将动态属性设置为'falsein the type. Strangely, if I post the document then it doesn't actually update the mapping, so if check_mapping`“filteredField”未列出，但是当我搜索文档时，filteredField 已被索引并且存在！ -
弹性版：
{
"name": "DpVBoAZ",
"cluster_name": "elasticsearch",
"cluster_uuid": "RX6axsbOTMatorw7s5AOXQ",
"version": {
"number": "5.2.0",
"build_hash": "24e05b9",
"build_date": "2017-01-24T19:52:35.800Z",
"build_snapshot": false,
"lucene_version": "6.4.0"
},
"tagline": "You Know, for Search"
}
但最终的 GET 会返回此文档，请注意 filteredField 是我添加到已发布文档中的一个字段，只是为了测试 - 它不应该出现在结果中。我还检查了映射，它已被动态添加到映射中。
我的创建索引查询有什么问题？？

我开始认为这是我对弹性映射工作原理的误解。我（有点明智地）假设如果一个字段没有被映射，那么该字段将不会存储在
_source中并且只会被删除。但是，弹性是否仍会将字段存储在 _source 中，但不会将字段映射保存到索引？这是我正在观察的。我保留字段的唯一选择是从源头进行过滤，然后发布一个完美的文档——真是太痛苦了。至少我可以通过将 strict 设置为 true 来阻止错误。但是如果该字段被丢弃会更好。谁能证实这一点？
