Class IndexSplitter
java.lang.Object
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
optimized, 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!
NOTE: this tool is unaware of documents added
atomically via IndexWriter.addDocuments(java.util.Collection)
or IndexWriter.updateDocuments(org.apache.lucene.index.Term, java.util.Collection)
, which means it can easily
break up such document groups.
