With CDS 2.0 spring update, PowerApps can now natively gets the data (any column) from lookup field (from another entity), which is a dramatic important feature, and it is fast!
However, the lookup field does not look like reachable via the search function, something has been natively available in Access Web Apps for instance, and Here I propose the idea to add this feature if it is not on the roadmap already.
