| <div class="markdown level0 remarks"><p><strong>NOTE:</strong> This handler assumes that <span class="xref">Lucene.Net.Index.IndexWriter</span> is not opened by |
| another process on the index directory. In fact, opening an |
| <span class="xref">Lucene.Net.Index.IndexWriter</span> on the same directory to which files are copied can lead |
| to undefined behavior, where some or all the files will be deleted, override |
| other files or simply create a mess. When you replicate an index, it is best |
| if the index is never modified by <span class="xref">Lucene.Net.Index.IndexWriter</span>, except the one that is |
| open on the source index, from which you replicate. |
| <p> |
| This handler notifies the application via a provided <see cref="T:Func{bool?}"></see> when an |
| updated index commit was made available for it. |
