测试方法：

                  SearchResultVo v1=new SearchResultVo();
		SearchResultVo v2=new SearchResultVo();
		SearchResultVo v3=new SearchResultVo();
		SearchResultVo v4=new SearchResultVo();
		SearchResultVo v5=new SearchResultVo();
		SearchResultVo v6=new SearchResultVo();
		SearchResultVo v7=new SearchResultVo();
		SearchResultVo v8=new SearchResultVo();
		SearchResultVo v9=new SearchResultVo();
		v1.setFullname("刘冰");
		v2.setFullname("刘伟");
		v3.setFullname("冰刘");
		v4.setFullname("刘建");
		v5.setFullname("冰刘e");
		v6.setFullname("冰刘a");
		v7.setFullname("刘志鹏");
		v8.setFullname("冰刘");
		v9.setFullname("冰的刘");
		
//		v1.setFullname("张凤连");
//		v2.setFullname("张月");
//		v3.setFullname("张大雷");
//		v4.setFullname("张月");
//		v5.setFullname("张楠");
//		v6.setFullname("张棋");
		List<SearchResultVo> list=new ArrayList<SearchResultVo>();
		list.add(v1);list.add(v2);list.add(v3);list.add(v4);list.add(v5);list.add(v6);list.add(v7);list.add(v8);list.add(v9);
		KeyWordComparator k=new KeyWordComparator(new SimpleSearchComparator());
		
		list=k.compare(list, "刘", 0);
                  //list=k.compare(list, "liu", 0);
		for(int i=0;i<list.size();i++)
		{
			System.out.println(list.get(i).getFullname());
		}

结果：

刘冰
刘建
刘伟
刘志鹏
冰刘
冰刘
冰刘a
冰刘e
冰的刘
