Before I used the pre_get_posts function to filter search results, now it does not work anymore

function search_filter_tax_query($query) {
    //if ( $query->is_search ){
	if ( $query->is_main_query() && is_search() ) {
	
	if(isset($_GET['stdc'])) { $tdc = $_GET['stdc']; } else { $tdc = ''; }
	if(isset($_GET['sorg'])) { $org = $_GET['sorg']; } else { $org = ''; }  
	if(isset($_GET['sbase'])) { $base = $_GET['sbase']; } else { $base = ''; }	
	if(  ( $tdc != '' ) || ( $org != '' ) || ( $base != '')  ) {
		
		$sub_args = array();				
		
		if( $tdc != '' ){ 
					$sub_args[0] =	array(
                        'taxonomy' => 'content_types',
                        'field' => 'term_id',						
                        'terms' => $tdc
                    );
				
				}
		if( $org != '' ){ 
					$sub_args[1] =	array(
                        'taxonomy' => 'content_origem',
                        'field' => 'term_id',
                        'terms' => $org
                    );
				
				}
		if( $base != '' ){ 
					$sub_args[2] =	array(
                        'taxonomy' => 'content_base',
                        'field' => 'term_id',
                        'terms' => $base
                    );
				
				}
	} 
      
      $query->set( 'tax_query', $sub_args );
    }
    return $query;
}
add_action( 'pre_get_posts', 'search_filter_tax_query' );

add_filter('query_vars', 'introduce_qvs');
function introduce_qvs($qv) {
    $qv[] = 'sorg';
	$qv[] = 'stdc';	
	$qv[] = 'sbase';
    $qv[] = 'sdti';
	$qv[] = 'sdtf';
    return $qv;
}

You have several alternatives to coding to do just that.

1) Use Toolset
Build you search page with an archive View, add your 3 filters to the view. WPSOLR will automatically convert the View query to an Elasticsearch query.
Here is the documentation: https://www.wpsolr.com/guide/configuration-step-by-step-schematic/activate-extensions/toolset-views-add-on/

2) Preselect facet values
With WPSOLR, you can filter by a facet value, like your taxonomy terms.
