using tags

[digging]

I am new to corel, it only took me about 1-1/2 to get registered for this. I just have a few questions about the Tags, went I enter a name in the Search (Tim), the results will be mostly of pictures with (Tim), but there are also other pictures that (Tim) is not in the picture, so my question when this happens how do I remove the other pictures and place them in the correct Tags? I a, just having such a hard time,I also have a vission problem.
