Nope. That map search is not tied to the data within the viz. The Devs told me it does prioritize results based on the data, but it does not limit the search to elements in your data set. I almost always turn the search option off for this reason. Someone could type Russia into that box on a U.S. map and be taken there.
I created an idea for this here: Create Option to Limit Map Search to Data Within the Viz.
