jQuery autocomplete sort

Hi,

I have problems with the jQuery autocomplete.
When i type the word "abc", then it will list all these results:

- abc something
- something abc
- someting else abc

All sentences containing the word "abc"
I only want to show results starting with "abc", how is that possible?
Have searched a lot and wasnt able to find anything :(

	<script>
		
		$(function() {
			var availableTags = <?php include($_SERVER['DOCUMENT_ROOT'].'/include/autocomplete.php'); ?>;
			$("#company-name").autocomplete({
				source: availableTags,
				autoFocus: true,
			});
		});
		
	</script>
