Lucene.net"DeleteDocuments"不删除文档

Question

我最近从nuget更新了Lucene.net,DeleteDocuments停止了工作.以下代码与我正在做的类似...这是从"orchard cms"复制的.我注意到类似的问题,但解决方案与我的情况无关.有人遇到同样的问题吗？

public void Delete(string indexName, IEnumerable<int> documentIds) {
    documentIds = documentIds.ToArray();

    if (!documentIds.Any()) {
        return;
    }

    using(var writer = new IndexWriter(indexName, new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_29), false, IndexWriter.MaxFieldLength.UNLIMITED)) {
        var query = new BooleanQuery();

        try {
            foreach (var id in documentIds) {
                query.Add(new BooleanClause(new TermQuery(new Term("id", id.ToString(CultureInfo.InvariantCulture))), Occur.SHOULD));
            }

            writer.DeleteDocuments(query);
        }
        catch (Exception ex) {
            Logger.Error(ex, "An unexpected error occured while removing the documents [{0}] from the index [{1}].", String.Join(", ", documentIds), indexName);
        }
    }
}
