我正在以1000个批量索引大数据 . 我有100000个文档 . 在中间，如果我直接从弹性搜索中删除索引（来自：http://localhost:9200/_plugin/head/），它将重新创建索引并索引新文档，以便丢失旧文档 . 如果索引不存在，我需要通过错误 . 下面是两条记录的json查询（实际为1000条）

接下来的1000批次将以相同的方式编入索引 . 我是否需要检查索引是否存在？或者有没有办法从ElasticSearch了解？

elasticsearch nest

    Elasticsearch将根据对象的结构自动创建索引，但请记住，任何自定义字段设置都不能以这种方式维护 .

    如果要检查索引是否存在，请使用：

    curl -XHEAD -i 'http://localhost:9200/your_index'

    或者等同于您使用的客户 .

    如果要停止自动创建索引，请将其添加到config / elasticsearch.yml：

    action.auto_create_index: false

    可以在这里找到：Automatic index creation
