also the following:
```
      if (totalMatchNum > 1) {
        self.countTag.hidden = false;
        self.countTag.classList.add('more');
      } else {
        self.countTag.hidden = true;
        self.countTag.classList.remove('more');
      }
```

can now be written
```
      self.countTag.hidden = (totalMatchNum <= 1);
      self.countTag.classList.toggle('more', (totalMatchNum > 1));
```
