Change in /plugins/advance-wp-query-search-filter/html/searchform.php line 16:

$args = array('hide_empty'=>$v['hide'],'exclude'=>$eid );

to

$args = array('hide_empty'=>$v['hide'],'include'=>$eid );

I found solution by myself. I modified that ts31os script

<?php
$taxonomy = ‘developer’;
$getTaxName = get_query_var($taxonomy);
$postsInCat = get_term_by(‘name’, $getTaxName, $taxonomy);
$postsInCat = $postsInCat->count;
echo $postsInCat;
?>
