lucene對數字和日期類型索引的創建

private int[] attachs = {1,4,6,2,3,8};
private Date[] dates = null;
//日期的初始化
private void datesInit() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        dates = new Date[6];
        try {
            dates[0] = sdf.parse("2010-12-01");
            dates[1] = sdf.parse("2011-12-01");
            dates[2] = sdf.parse("2001-12-01");
            dates[3] = sdf.parse("2013-12-01");
            dates[4] = sdf.parse("2003-12-01");
            dates[5] = sdf.parse("2014-12-01");
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
//給數字加索引
                doc.add(new NumericField("attach", Field.Store.YES,true).setIntValue(attachs[i]));
                //給日期加索引
                doc.add(new NumericField("date",Field.Store.YES,true).setLongValue(dates[i].getTime()));
