Using the default search, the ExpertPlug search shows first the results for the exact location you selected sorted by most recent date first, then the results for the region or state of this location, then for the country.
Example: If you search is in "Los Angeles" you will first have all results for Los Angeles, then for California, then for United States. If your search if for "France", you'll have directly all the results in France and all regions or cities in France sorted by date.
Searching with exact location match indicator selected, you will have only the results exactly matching your location search. For instance if searching elements in "Los Angeles" you will have only results in Los Angeles.
