Lightroom CC: The keyword icon is not active in my search function. Anybody know why?

Hi David,

Would you post a screenshot along with your system information?

Hi David,

When you filter, the filters that don't apply will be inactive.  In your case, this would happen if you don't actually have keywords applied to your images.  Try switching to a different album or All Photos to broaden the set of photos to include ones that have keywords.
