Override SearchWP's term accent removal

functions.php

<?php

function my_searchwp_leinent_accent_result( $string, $original_string ) {
  
  if ( 'mytést' == $original_string ) {
    $string = 'mytest';
  }
  
  return $string;
}

add_filter( 'searchwp_leinent_accent_result', 'my_searchwp_leinent_accent_result', 10, 2 );
