I have changed my code to use the delete function of the writer and this
doesn't work either. Here's my code:
private void indexDocument(IndexWriter writer, Document document, File file)
throws CorruptIndexException, IOException
{
writer.deleteDocuments(new
Term(IDHConstants.FILE_ID,FileNameUtil.getFileId(file)));
document.add(new Field(IDHConstants.DATE_LAST_INDEX, DateUtil.formatDate(new
Date()), Field.Store.YES, Field.Index.TOKENIZED));
writer.addDocument(document);
}

Yes it is because you have IndexWriter open while you are trying to
delete using the IndexReader. You should close the IndexWriter first and
then delete using IndexReader, or else use the delete() function of the
IndexWriter itself...
