title: Search all user by user's full name in firebase IOS
body: <p>I have added <code>UISearchBar</code> and <code>UITableView</code> in my project. I need to filter all the users according to the text in <code>UISearchBar</code> and display in the tableview. I do research for the query in firebase documentation but I did not find. I just need the firebase query for partial string. Can any one help me? </p>
