UI autocomplete - best practices - get multiple result


Greetings:
Please provide suggestions on the best practices for obtaining the
current results of a multiple choice autocomplete.
I understand that i can use the formatResult callback to obtain the
data element each time a user makes a selection. I can then push this
onto an array. What if a user removes a result though?
Is there a way to, at any time (such as the click method of a save
button), to obtain the final list of elements stored in the
autocomplete?
Thanks
