I have working the search with this modification.
Check that you have not made ??a mistake by changing the search.php code (ie, if you left some brace unlocked, etc. ..)

You need a default page for File Browser:

The search widget need to set a default page in WP-Filebase -> Settings -> File Browser

Do you set this?

Change this:

if(empty($s)) {
		$s = empty($wp_query->query_vars['s']) ? (empty($_GET['s']) ? null : stripslashes($_GET['s'])) : $wp_query->query_vars['s'];
		if(empty($s)) return null;
}

to…

if(empty($s)) {
		$s = empty($wp_query->query_vars['s']) ? (empty($_GET['s']) ? null : stripslashes($_GET['s'])) : $wp_query->query_vars['s'];
		if(empty($s)) {
			$s = empty($wp_query->query_vars['wpfb_s']) ? (empty($_GET['wpfb_s']) ? null : stripslashes($_GET['wpfb_s'])) : $wp_query->query_vars['wpfb_s'];
		}
		if(empty($s)) return null;
	}

I have fixed this…

In the file wp-content/plugins/wp-filebase/classes/Search.php
In the function SearchWhereSql, before the line:
if(empty($s)) return null;

Add this line:

....
if(empty($s)) {
			$s = empty($wp_query->query_vars['wpfb_s']) ? (empty($_GET['wpfb_s']) ? null : stripslashes($_GET['wpfb_s'])) : $wp_query->query_vars['wpfb_s'];
		}
if(empty($s)) return null;

Note: the search widtget need to set a default page in WP-Filebase -> Settings -> File Browser
