title: Search View with Room
body: <p>I am trying to find a way to get data from <code>Room</code> when searching on Search bar. My database has 200000 rows of data.</p>
  
  <p>I have found a relative article <a href="http://www.zoftino.com/android-search-functionality-using-searchview-and-room" rel="nofollow noreferrer">http://www.zoftino.com/android-search-functionality-using-searchview-and-room</a>, but it is wrong. He registers an observer everytime the text changes. Is there another way?</p>
