note.txt

どうも似たようなハッシュタグが多いと引っかかりにくいみたい＜通常のTwitterのサーチ検索
Twitter4jの検索とは逆に古い順で取得されるので逆順につめておく必要があり
（最新をtopにしたい場合


firstpost_date等はunix timestampなので

String timeStamp = item.getString("firstpost_date");//jsonObject
java.util.Date time=new java.util.Date(Long.valueOf(timeStamp)*1000);
の形で変換

d:day
w:week
m:month
