 $('#search-field').autocomplete({source: function(){
       jQuery.post('url', data, function(dataReceived){globalVariable = dataReceived; }, 'json');
   },

   select: function(event, ui) { 
      var local = globalVariable[ui.item];
      // work with the local variable.
 }

$(document).ready(function(){

var dataSource= [{"title":"some-title","link":"/searc?q=some-title"}, {"title":"some-title2","link":"/searc?q=some-title2"}];
