How to make RayCast ignore a specific tag?

Hi, I'm using raycast to let the player know whether he has hit a enemy in my game.

Code (CSharp):

1. RaycastHit hit;
2.     Ray ray = new Ray (startPoint, direction);
3.     bool isHit = Physics.Raycast (ray, out hit, rayLength);
4.           if (isHit && hit.collider.tag == EnemyTag)) {
5.                //bull's eye!
6.     }

I want the bullet can hit a enemy who stand behind his illusion, but the problem is that Raycast seems only return the first object it hits(via RaycastHit). Is that anyway to make Raycast ignore the illusion tag? Thanks!

 

I just realize there's a RaycastAll() could be the key

 

It would be easier if you used layers instead of tags, since raycasts can easily ignore layers.
