从索引中删除一个文档后,通过 IndexWriter.UpdateDocument 更新同样的文档在 IndexWriter.Commit 提交时报错

问题是并发更新索引引起的,改为以队列方式更新索引后问题就消失了,目前队列用的是 Coravel 的 IQueue,接下来准备基于 dapr 实现(本来就是订阅 dapr 消息更新索引的) https://q.cnblogs.com/q/142679/

就Lucene.Net来说,“Could not find file '_bkd.cfs'”这一错误通常是由于Lucene保存文档和加载文档时出现问题所造成的。可以尝试使用IndexWriter中的RemoveDocument()方法来将文档删除,并使用IndexWriter的AddDocument()方法重新添加一个文档进行更新。
