      if (!text) return text;

      var targetAttr = "";
      if (angular.isDefined(target)) {
          targetAttr = ' target="' + target + '"';
      }

      // replace #hashtags
      var replacePattern1 = /(^|\s)#(\w*[a-zA-Z_]+\w*)/gim;
      replacedText = replacedText.replace(replacePattern1, '$1<a href="https://twitter.com/search?q=%23$2"' + targetAttr + '>#$2</a>');
