There is no global filter or search object that quite works in this way, where it will return all fields, members, etc with the string typed. A global filter can be added for a specific field and the wildcard match quick filter can be used to return that member in a specific field on every page connected to that data source. However, that is about as close as we currently have to your desired functionality. This might be a good one to place under Ideas in the Community.
Hope this helps!
