| <section><p>Command-line tool for extracting sub-files out of a compound file.</p> |
| </section> |
| <h4><a class="xref" href="Lucene.Net.Index.IndexSplitter.html">IndexSplitter</a></h4> |
| <section><p>Command-line tool that enables listing segments in an |
| index, copying specific segments to another index, and |
| deleting segments from an index.</p> |
| <p>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.</p> |
| |
| <div class="lucene-block lucene-experimental">This is a Lucene.NET EXPERIMENTAL API, use at your own risk</div><p> You can easily |
| accidentally remove segments from your index so be |

| <h4><a class="xref" href="Lucene.Net.Index.MultiPassIndexSplitter.html">MultiPassIndexSplitter</a></h4> |
| <section><p>This tool splits input index into multiple equal parts. The method employed |
| here uses <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Index.IndexWriter.html#Lucene_Net_Index_IndexWriter_AddIndexes_Lucene_Net_Index_IndexReader___">AddIndexes(IndexReader[])</a> where the input data |
| comes from the input index with artificially applied deletes to the document |
| id-s that fall outside the selected partition. |
| <p>Note 1: Deletes are only applied to a buffered list of deleted docs and |
| don't affect the source index - this tool works also with read-only indexes. |
| </p> |
| <p>Note 2: the disadvantage of this tool is that source index needs to be |
| read as many times as there are parts to be created, hence the name of this |
| tool.</p> |
| <p> |
| <p><strong>NOTE</strong>: this tool is unaware of documents added |
| atomically via <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Index.IndexWriter.html#Lucene_Net_Index_IndexWriter_AddDocuments_System_Collections_Generic_IEnumerable_System_Collections_Generic_IEnumerable_Lucene_Net_Index_IIndexableField___Lucene_Net_Analysis_Analyzer_">AddDocuments(IEnumerable<IEnumerable<IIndexableField>>, Analyzer)</a> or |

| break up such document groups. |
