title: how to implement search box in my application in android?
body: <p>i have one activity in my android application in which a list of orders is populated. I want to implement a search functionality on this activity so that user can search for particular order. </p>
  
  <p>I have read about the search box facility provided by adding a <code>searchable.xml</code> file in the application but I am not able to make it work for me?</p>
  
  <p>I just want to add a search box in the activity and search for specific data in database.
  How can I do this?</p>
