删除Lucene.net中的所有索引 [英] Delete all indices in Lucene.net

问题描述

我想删除所有先前创建的索引.我正在使用Lucene.net.

I want to delete all the previously created indices. I am using Lucene.net.

我尝试了以下操作:

Term term = new Term(); //empty because I want to delete all the indices
IndexReader rdr = IndexReader.Open(_directory);

rdr.DeleteDocuments(term);
rdr.Close();

但是我得到了错误.知道怎么做吗?

But I get error. Any idea how to go about it?

推荐答案

删除索引的最佳方法是擦除文件系统目录.但是，如果您不想重新生成索引，最简单的方法是使用create参数为true打开一个新的索引编写器.它将启动一个新索引，删除现有索引的内容.

The best way to delete an index is to wipe the filesystem directory. However, if you wan't to regenerate the index, the easiest way is to open a new indexwriter with the create parameter as true. It will start a new index deleting the contents of the existing one.
