| </h1> |
| <div class="markdown level0 summary"><p>This is an easy-to-use tool that upgrades all segments of an index from previous Lucene versions |
| to the current segment file format. It can be used from command line:</p> |
| <pre><code> java -cp lucene-core.jar Lucene.Net.Index.IndexUpgrader [-delete-prior-commits] [-verbose] indexDir</code></pre> |
| <p>Alternatively this class can be instantiated and <a class="xref" href="Lucene.Net.Index.IndexUpgrader.html#Lucene_Net_Index_IndexUpgrader_Upgrade">Upgrade()</a> invoked. It uses <a class="xref" href="Lucene.Net.Index.UpgradeIndexMergePolicy.html">UpgradeIndexMergePolicy</a> |
| and triggers the upgrade via an <a class="xref" href="Lucene.Net.Index.IndexWriter.html#Lucene_Net_Index_IndexWriter_ForceMerge_System_Int32_">ForceMerge(Int32)</a> request to <a class="xref" href="Lucene.Net.Index.IndexWriter.html">IndexWriter</a>. |
| <p> |
| This tool keeps only the last commit in an index; for this |
| reason, if the incoming index has more than one commit, the tool |
| refuses to run by default. Specify <code>-delete-prior-commits</code> |
| to override this, allowing the tool to delete all but the last commit. |
| From .NET code this can be enabled by passing <code>true</code> to |
| <a class="xref" href="Lucene.Net.Index.IndexUpgrader.html#Lucene_Net_Index_IndexUpgrader__ctor_Lucene_Net_Store_Directory_Lucene_Net_Util_LuceneVersion_System_IO_TextWriter_System_Boolean_">IndexUpgrader(Directory, LuceneVersion, TextWriter, Boolean)</a>. |
| <p> |
| <strong>Warning:</strong> this tool may reorder documents if the index was partially |
| upgraded before execution (e.g., documents were added). If your application relies |
| on "monotonicity" of doc IDs (which means that the order in which the documents |
| were added to the index is preserved), do a full ForceMerge instead. |
| The <a class="xref" href="Lucene.Net.Index.MergePolicy.html">MergePolicy</a> set by <a class="xref" href="Lucene.Net.Index.IndexWriterConfig.html">IndexWriterConfig</a> may also reorder |
| documents.</p> |
