[wp-hackers] meta_value contains text

[Jörn Röder]

Hi,
i have some trouble with the query_posts() and meta_value-Parameter
if i try query_posts('meta_value=New York') it works, but with  
'meta_value=New' i get no results even though it was included in 'New  
York'…

Is there a "meta_compare-Value" that is not mathematical and contain  
works?

Thanks Jörn
