Smart Album Boolean Operators

When creating a Smart Album, the only boolean operator when using different search rules is AND. Other options typically available for computer searches are OR and NOT.

This is what I would like from a smart album in LrD:

People = John Doe

OR

Keyword = John Doe

However, this is the only option available now:

People = John Doe

AND

Keyword = John Doe

Attached is a screenshot showing AND being the only way to create a Smart Album when there is more than one rule.
