Recount posts in terms

Hi there,

I have written a PHP snippet that conditionally add a tax_query in the wpc_filtered_query_end action. However, when the custom tax_query is activated, the counts of posts in the terms in other filters is wrong.

Is there some other place, the query should be changed, or should I call an action in order to refresh the count?

The code for reference

function expand_search($query) {
	if (!is_admin() && null != $query->get('s') && '' != $query->get('s') && !empty($query->get('s'))){
		$search_query_term = $query->get('s');
		
		if (!$search_query_term) return;
		
		// Split the search query into terms
		$query_terms = explode(' ', $search_query_term);
		$query_terms[] = $search_query_term; // Add the full search term to the array
		$query_terms = array_map('sanitize_text_field', $query_terms); // Sanitize each term
		
		// Initialize arrays for matching term IDs
		$matching_forfattere = array();
		$matching_temaer = array();
		
		// Loop through each term and add matching forfatter and category term IDs
		foreach ($query_terms as $query_term) {
			$forfatter_terms = get_terms(array(
				'taxonomy' => 'forfatter',
				'fields' => 'ids',
				'name__like' => $query_term,
				'hide_empty' => false,
			));
			
			$temaer_terms = get_terms(array(
				'taxonomy' => 'category',
				'fields' => 'ids',
				'name__like' => $query_term,
				'hide_empty' => false,
			));
			
			// Merge the IDs to avoid overwriting in each iteration
			$matching_forfattere = array_merge($matching_forfattere, $forfatter_terms);
			$matching_temaer = array_merge($matching_temaer, $temaer_terms);
		}
		
		// Remove duplicate IDs from the arrays
		$matching_forfattere = array_unique($matching_forfattere);
		$matching_temaer = array_unique($matching_temaer);
		
		if (!empty($matching_forfattere) || !empty($matching_temaer)) {
			$query->set('s', '');
			
			// Get any existing tax_query and combine it with the new one
			$existing_tax_query = $query->get('tax_query') ?: array();
			
			// Add our custom tax queries
			$custom_tax_query = array(
				'relation' => 'OR',
				array(
					'taxonomy' => 'forfatter',
					'field' => 'term_id',
					'terms' => $matching_forfattere,
				),
				array(
					'taxonomy' => 'category',
					'field' => 'term_id',
					'terms' => $matching_temaer,
				),
			);
			
			// Merge existing tax_query with custom_tax_query
			$merged_tax_query = array_merge($existing_tax_query, array($custom_tax_query));
			
			// Set the combined tax_query
			$query->set('tax_query', $merged_tax_query);
		}
	}
