关于Lucene搜索框架中的问题

public class Search {

public static void main(String[] args) throws Exception{

Search search = new Search();
search.createIndex();
search.indexSearch();
}

public void indexSearch() throws Exception{

IndexSearcher searcher = new IndexSearcher(Config.INDEX_PATH);

Term t = new Term("bookname", "钢铁");
Query query = new TermQuery(t);

Hits hits = searcher.search(query);

for(int i = 0;i<hits.length();i++){
System.out.println(hits.doc(i));
System.out.println(hits.score(i));
System.out.println(hits.id(i));
System.out.println("==============");
}
System.out.println(query);
System.out.println("以上为查询结果");
}

public void createIndex() throws Exception{

IndexWriter writer = new IndexWriter(Config.INDEX_PATH, new StandardAnalyzer(), true);

Document document1 = new Document();
Document document2 = new Document();
Document document3 = new Document();
Document document4 = new Document();
Document document5 = new Document();
Document document6 = new Document();
Document document7 = new Document();
Document document8 = new Document();
/*如果用这段则含有“钢铁”字符的条目都会被搜索出来
