我得到有关索引的以下信息：
curl -XGET 'http://XXX.XX.XX.XX:9200/_cat/indices?v'
health status index pri rep docs.count docs.deleted store.size pri.store.size
yellow open news_abc 1 1 8983616 3008123 6.5gb 6.5gb
似乎有一个数据。然后我想要检索一些数据。为此，我运行此代码：
curl -XGET 'http://XXX.XX.XX.XX:9200/news_abc'
并获得以下结果：

但是，我想从映射myitem获取数据：
curl -XGET 'http://XXX.XX.XX.XX:9200/news_abc/myitem'
错误：
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"No feature for name [myitem]"}],"type":"illegal_argument_exception","reason":"No feature for name [myitem]"},"status":400}
答案 0 :(得分：0)
试试这个 -
curl -XGET＆＃39; XXX.XX.XX.XX：9200 / news_abc / _search？pretty＆＃39 ;;
这将为您提供一个＆＃34; _source＆＃34; json响应中的字段。这个＆＃34; _source＆＃34;文件将包含＆＃34; myitem＆＃34;领域及其价值观。
然后，您可以使用过滤器和聚合来使用＆＃34; -d＆＃34;来获取该字段中的所有值。 curl的参数。
