Query to find word in login field in Users Resource API V2

Hi,

I am trying to create a query in where I can search for a cetain term inside the login property in the users resource.

So i just realize that I can't use MATCHES here and the following query only return results if the login parameter is exactly the same as the search parameter

 $url = "https://api.lithium.com/community/2.0/".$tenantId."/search?q=SELECT+login%2Cview_href%2Cavatar+FROM+users+WHERE+login%3D'".$searchTerm."'+LIMIT+".$numberOfResults."&api.pretty_print=true";

 Is there anything like a LIKE clause that I can use in LIQL, or smarter way to write this query? 

What want is that if the user looks for Pat I can retrieve results like Patricia, or Patrick or Patau... things like that

Thanks for your help
