How to access value passed from autocmplete.('search','thevalue') in the autocomplete search event?

How to access value passed from autocmplete.('search','thevalue') in the autocomplete search event?

I have a call to the search method

$('myelem').autcomplete('search','thevalue');

and have an event handler for the search event

search: function (e, ui){

var value=?? //need to acces "thevalue" here

}

where I need to access "thevalue" in the body of the function. Is the search method value passed to the search event in some way?

Thanks,
Chris
