问题

迁移寻古诗词网时，ElasticSearch 由 7.8 升级到 8.7 了。使用 BulkAll 索引数据时，会报错误：BulkAll halted after receiving failures that can not be retried from _bulk

解决办法

目前最新的的Nest版本是7.17.5，通过调用 .EnableApiVersioningHeader() 启用兼容模式即可解决

IConnectionPool pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));

var settings = new ConnectionSettings(pool)
    .EnableApiVersioningHeader();
