Class IndexSplitter

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 Stream) so it will not work with non FSDirectory Directory impls.

Note

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!

LUCENENET specific: In the Java implementation, this class' Main method was intended to be called from the command line. However, in .NET a method within a DLL can't be directly called from the command line so we provide a .NET tool, lucene-cli, with three commands that map to that method: index copy-segments, index delete-segments, and index list-segments
