Search results show results of all taxonomies

Hi,

I have the following issue. I work with a lot of taxonomies.
For the taxonomy country and region I have taxonomy archives.
For example: Taxonomy country france I have a page:
https://www.sitename.nl/country/france

for a region I have https://www.sitename.nl/region-france/regionname

At every taxonomy archive I’ve added a filter form, where the user can filter with from several different taxonomies. Issue is that when I filter at the page of France, it shows results from (as example) Italy as well.

I’m using a custom function to show the results. I know I’ll have to add something like:

$arg = array(
	'country' => 'france'
);

	$query = new WP_Query( $arg );

only changing ‘country’ => ‘france’ to something that automatically the right taxonomy etc. is added to the array.

When i’m at the region page it should add: ‘region-country’ => ‘region-name’.

Any clue how to do this?
