backbone.js view return false -

can explain me, in backbone.js view return false statement. example

search: function() {   var view = this;   $.post('/contacts/find',     this.$('form').serialize(), function(data) {     view.render(data);   }).error(function(){     $("#results").text('no contacts found.');     $("#results").slidedown();   });   return false; }, 

to cancel default event behaviour. in example after clicking submit button form not submitted (page reload). same as:

event.preventdefault(); event.stoppropagation();
