elasticsearch - 如何将not_analyzed应用于字段

Question

我正在尝试将 not_analyzed 添加到网址字段。我尝试使用字段类型字符串给它未能解析映射[doc]:没有在字段[url] 上声明类型[string]的处理程序，我用文本替换了该类型，但我得到了未能解析映射[ doc]:无法将[url.index]转换为boolean 异​​常。我怎样才能使归档的URL not_analyzed

 PUT /some_index

Elasticsearch 5.0删除了not_analyzed设置。在其位置上，string类型分为两部分:已分析的text和未分析的keyword。在此博客文章上阅读更多信息:Strings are dead, long live strings!

假设您正在运行5.0+，则您的映射具有非法值。而且，这是冲突的:您说您不想分析url，但是您指定了一个分析器:"search_analyzer": "my_analyzer"
如果不想分析该字段，则应将url字段设置为与主机相同的设置:

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

否则，输入text:

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