java Lucene的近实时搜索实现

Question

这是我在lucene中搜索东西的代码

        ScoreDoc[] hits = null;
        StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_35);
        QueryParser q = new QueryParser(Version.LUCENE_35, "content", analyzer);
        Query query = q.parse(searchString);

        IndexReader reader = IndexReader.open(IndexWriterSingleton.getIndexWriter(), true);
        IndexSearcher is = new IndexSearcher(reader);
        // IndexSearcher is = new IndexSearcher(index, true);
        TopScoreDocCollector collector = TopScoreDocCollector.create(100, true);
        is.search(query, collector);
        hits = collector.topDocs().scoreDocs;

我的问题是：这一行（仅这一行）是否使搜索接近实时

IndexReader reader = IndexReader.open(IndexWriterSingleton.getIndexWriter(), true);

我维护一个IndexWriter（不在任何地方关闭它）

不要让你的生活变得困难。使用NRTManager类来处理所有这些
