result.entities.urls[0].expanded_urlfetch = function(query) {
	var script_tag = document.createElement("script");
	script_tag.id = "fetcher";
	script_tag.src = "https://search.twitter.com/search.json"+query+"&callback=parse";
	document.body.appendChild(script_tag);
}

parse = function(data) {
	document.body.removeChild(document.getElementById("fetcher"));
	if( data && data.results ) {
		for( var i = 0, len = data.results.length; i < len; i++ ) {
			var result = data.results[i];
			if( result.entities.urls[0].display_url ) {
				if( result.entities.urls[0].expanded_url.indexOf("http://vine.co/v/") != -1 ) {
					console.log( result.entities.urls[0].expanded_url );
					vine_urls.push( result.entities.urls[0].expanded_url );
				}
			}
		}
	}

var vine_urls = new Array();
$(document).ready(function() {
	fetch("?q=vine.co%2Fv%2F&result_type=recent&include_entities=1&rpp=20");
