Wordpress : how to search a user by username in wordpress

I am trying to do an {Ask for a challange } button under online games posts in WordPress, so the user will choose another user form a search box and send a request for it with the link of the game,but I have no idea how to do this,

so as a start I tried this code so it can show me if the search method works or not but it didn't, also it is my first time to create a search box so .. here it is: 

<?php 
 global $wpdb ;
if($_POST){

    $search_input = $_POST['chs'];
    if(username_exists($search_input)){
        print_r($search_input)  ;

    }else {
        print_r("there is no username by this");
    }
}

?>

<html>
    <head>

    </head>
    <body>
        <form method="post">
            <p> would you challenge your friends ? </p>
            <input type="text" name="chs" id="chs" >
            <button type="submit"> Challenge</button>
        </form>

    </body>

</html>

in this code I want it to return the searched username if it is existed, but then I need to return suggestions of usernames that could match the entries. ex: if the user is typing "mf" it will return the best suggestions of usernames according to what the user types and then the user choose from them.

You can use the get_user_by() to get the User information by username

<?php
$user = get_user_by( 'login', $username);

if ( $user !== false){
   // User with the username is found. Do your work
} else {
   // User with the username is not found.
}
?>
