\<%= observe\_field ‘search\_form’,  
:frequency =\> 0.5,  
:update =\> ‘results’,  
:url =\> { :controller =\> ‘users’, :action =\> ‘get\_results’ },  
:loading =\> “Element.show(‘indicator\_gif\_id’)”,  
:complete =\> “Element.hide(‘indicator\_gif\_id’)”,  
:with =\> “‘search\_text=’ + value” %\>

How do I add effects in this?]

Thanks
