      if (value === '+' || value === '+1') {
        return [this.emojisList['+1']];
      }

      let values = value.toLowerCase().split(/[\s|,|\-|_]+/);
      let allResults = [];

      if (values.length > 2) {

        categories.forEach(category => {

            return;
          }

          category.emojis.forEach(
            emojiId => {
              // Need to make sure that pool gets keyed
              // with the correct id, which is why we call emojiService.getData below
