示例1: CopyVectorsNoDeletions

		private void  CopyVectorsNoDeletions(TermVectorsWriter termVectorsWriter, TermVectorsReader matchingVectorsReader, IndexReader reader)
		{
			int maxDoc = reader.MaxDoc;
			if (matchingVectorsReader != null)
			{
				// We can bulk-copy because the fieldInfos are "congruent"
				int docCount = 0;
				while (docCount < maxDoc)
				{
					int len = System.Math.Min(MAX_RAW_MERGE_DOCS, maxDoc - docCount);
					matchingVectorsReader.RawDocs(rawDocLengths, rawDocLengths2, docCount, len);
					termVectorsWriter.AddRawDocuments(matchingVectorsReader, rawDocLengths, rawDocLengths2, len);
					docCount += len;
					checkAbort.Work(300 * len);
				}
			}
			else
			{
				for (int docNum = 0; docNum < maxDoc; docNum++)
				{
					// NOTE: it's very important to first assign to vectors then pass it to
					// termVectorsWriter.addAllDocVectors; see LUCENE-1282
