You are using single quotes (') for your $search string. Variables aren't parsed inside single quotes. So the search string right now is literally '/$_GET[word]/i'

It's a regular expression so the correction would be

$search = "/$_GET[word]/i";

It works for all letters, you just can't use a variable inside single quotes.

$myVar = 'Hello World';
$string = '/$myVar/'; //== /$myVar/
$string = "/$myVar/" //== /Hello World/
$myVar = 'Hello World';
$string = '/$myVar/'; //== /$myVar/
$string = "/$myVar/" //== /Hello World/
