Hello
That would require modify code. Look at the file components/com_osmembership/model/members.php, find this line of code:
Code:
$config['search_fields'] = ['tbl.first_name', 'tbl.last_name', 'tbl.membership_id', 'tbl.email', 'b.title', 'c.username', 'c.name'];
Change it to:
Code:
$config['search_fields'] = ['tbl.country', 'tbl.state', 'tbl.city'];
Then check to see if it works?
Regards,
Tuan
