Lucene查询找到给定距离的令牌

Question

我已经将文件内容索引为Luence（4.9）中的字符串，以下是一些在Lucene中编入索引的示例数据。

Info Object 
{ 
  String ID;
  String infoData;
} 

ID infoData

1 Distance so far travelled 10KM

2 Distance travelled 5Miles

3 distance covered 100 Meter

 doc.add(new TextField("id", info.getID(), Field.Store.YES));
 doc.add(new TextField("pdata", infoData.toString().replaceAll("(?m)^\\s", ""), Field.Store.NO));
 writer.addDocument(doc);

我正在尝试搜索以下术语并期望输出第一条记录，但我没有得到任何东西：

Term query - Distance KM
Expected output - ID = 1

 SpanNearQuery query = new SpanNearQuery(new SpanQuery[] { new SpanTermQuery(new Term("pdata", "Distance")),
            new SpanTermQuery(new Term("pdata", "KM")) }, 3, true);
    TopDocs hits = searcher.search(query, 20);
    ScoreDoc[] scoreDocs = hits.scoreDocs;
    System.out.println("Results  :" + hits.totalHits);
    for (ScoreDoc match : scoreDocs)
    {

        Document doc = searcher.doc(match.doc);
        System.out.println(doc.get("id"));

    }

我有什么遗失的吗？
