Searching within view widgets is showing unwanted results

Hello community, 

I have a view widget set up that allows a user to explore content grouped by Nations.

If I navigate into the views, I can see the content that I want.  However, if at this level, I search on a value at this top level (without going into each sub-view), hubshare is searching for all objects in the M-Files database and not just for the one highlighted below. 

How can I stop this from happening?  Because users are likely to search at this level without going into the individual nations' views.

Thanks in advance,

Irene
