How to use the querystring.escape function in querystring

function researchMovie(show,context) {
	// _logger.debug(show);
	var showName = show['title'];
	_logger.debug("Researching for : " + showName);
	showName = showName.replace(/\([0-9]*\)/gmi, "").trim();
	showName = showName.replace(/\((US|FR|ES)\)/gmi, "").trim();
	showName = showName.replace(/['|"](s)*/gmi, "").trim();
	showName= require('querystring').escape(showName);

	_logger.debug("Clean Name : "+showName);
	var query = (context.req.query.q) ? context.req.query.q : showName;

	research( baseUrl + "/torrents/search/"+query ,reponseSearch.bind( {context: context} ),context.req.query);
}
