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