Class IndexSplitter

java.lang.Object
  extended by org.apache.lucene.index.IndexSplitter

public class IndexSplitter
extends Object

Command-line tool that enables listing segments in an index, copying specific segments to another index, and deleting segments from an index.

This tool does file-level copying of segments files. This means it's unable to split apart a single segment into multiple segments. For example if your index is a single segment, this tool won't help. Also, it does basic file-level copying (using simple File{In,Out}putStream) so it will not work with non FSDirectory Directory impls.

WARNING: This API is experimental and might change in incompatible ways in the next release.
You can easily accidentally remove segments from your index so be careful!
