如何将 not_analyzed 应用于字段

Question

我正在尝试将 not_analyzed添加到 url 字段。我尝试使用它给我的字段类型字符串无法解析映射[doc]：没有在字段[url]上声明的类型[字符串]的处理程序，并且我用文本替换了类型，并且我得到了无法解析映射[doc]：无法将 [url.index] 转换为布尔异常。如何使提交的 url not_analyzed

Elasticsearch 5.0 删除了该not_analyzed设置。取而代之的是，该string类型被分为两种：text哪个被分析，keyword哪个不被分析。阅读这篇博文了解更多内容：弦乐已死，弦乐万岁！

假设您运行的是 5.0+，则您的映射具有非法值。另外，它是冲突的：你说你不希望url被分析，但你指定了一个分析器："search_analyzer": "my_analyzer"

如果您不想分析该字段，则应将 url 字段设置为与主机相同：

"url": {
    "type": "keyword"
}

否则，创建类型text：

"url": {
    "type": "text",
    "search_analyzer": "my_analyzer"
}
