C# Class Lucene.Net.Index.Sorter.SortingAtomicReader

An AtomicReader which supports sorting documents by a given Sort. You can use this class to sort an index as follows:

 IndexWriter writer; // writer to which the sorted index will be added DirectoryReader reader; // reader on the input index Sort sort; // determines how the documents are sorted AtomicReader sortingReader = SortingAtomicReader.Wrap(SlowCompositeReaderWrapper.Wrap(reader), sort); writer.AddIndexes(reader); reader.Dispose(); // alternatively, you can use a using block writer.Dispose(); // alternatively, you can use a using block
