问题: 索引中 老人头男皮带(505J014L)包邮 被分为 老人头 | 老人 | 人头 ，而我输入的老人头 被分为 老 | 人头，导致搜索不到结果，请问这样的原因是什么？如何处理？

1. 你开启了index模式
2. 既然都有人头，就可以搜索到，你说的搜不到根本不成立：

Analyzer analyzer = new HanLPIndexAnalyzer();////////////////////////////////////////////////////
        IndexWriterConfig config = new IndexWriterConfig(analyzer);
        config.setOpenMode(IndexWriterConfig.OpenMode.CREATE);
        Directory directory = new RAMDirectory();
        IndexWriter indexWriter = new IndexWriter(directory, config);

        Document document = new Document();
        document.add(new TextField("content", "[新闻]服务大众。", Field.Store.YES));
        indexWriter.addDocument(document);

        document = new Document();
        document.add(new TextField("content", "[经济学]商品和服务", Field.Store.YES));
        indexWriter.addDocument(document);

        document = new Document();
        document.add(new TextField("content", "[服装店]老人头男皮带", Field.Store.YES));
        indexWriter.addDocument(document);

        indexWriter.commit();
        indexWriter.close();

        IndexReader ireader = DirectoryReader.open(directory);
        IndexSearcher isearcher = new IndexSearcher(ireader);
        QueryParser parser = new QueryParser("content", new HanLPAnalyzer());
        Query query = parser.parse("老人头");
        ScoreDoc[] hits = isearcher.search(query, 300000).scoreDocs;
        assertEquals(1, hits.length);
        for (ScoreDoc scoreDoc : hits)
        {
            Document targetDoc = isearcher.doc(scoreDoc.doc);
            System.out.println(targetDoc.getField("content").stringValue());
        }
