get_users($args) returns duplicate users

Hi,

I have still the same problem…

After some searching, I discovered that this code/search request:

//search args
$args = array(
		'blog_id'      => $GLOBALS['blog_id'],
		'orderby'      => 'user_nicename',
		'order'        => 'ASC',
		'search'       => $search,
		'count_total'  => true,
		'fields'       => 'all',
		'number'       => '',
		'meta_key'     => '',
		'meta_value'   => '',
		'meta_compare' => '',
		'meta_query'   => array(),
);
//get the users and diplay them
$blog_users = get_users($args);

Results in this query by the WordPress-core:

SELECT wp_users . *
FROM wp_users
INNER JOIN wp_usermeta ON wp_users.ID = wp_usermeta.user_id
WHERE ‘1’ = ‘1’
AND (
(
wp_usermeta.meta_key = ‘wp_s2member_subscr_id’
AND wp_usermeta.meta_value LIKE ‘%asdf%’
)
OR (
wp_usermeta.meta_key = ‘wp_s2member_custom’
AND wp_usermeta.meta_value LIKE ‘%asdf%’
)
OR (
wp_usermeta.meta_key = ‘wp_s2member_custom_fields’
AND wp_usermeta.meta_value LIKE ‘%asdf%’
)
OR (
wp_usermeta.meta_key = ‘wp_s2member_notes’
AND wp_usermeta.meta_value LIKE ‘%asdf%’
)
OR (
wp_usermeta.meta_key LIKE ‘%_name’
AND wp_usermeta.meta_value LIKE ‘%asdf%’
)
OR user_login LIKE ‘%asdf%’
OR user_nicename LIKE ‘%asdf%’
OR user_email LIKE ‘%asdf%’
OR user_url LIKE ‘%asdf%’
OR display_name LIKE ‘%asdf%’
)
AND wp_users.ID
IN (

SELECT DISTINCT (
user_id
)
FROM wp_usermeta
WHERE meta_key = ‘wp_capabilities’
)
ORDER BY user_nicename ASC
LIMIT 0 , 30

Looking at all those OR fields to search for, I understand that there are so many results. So what am I doing wrong? My goal is to search for all users with that name in them.

Tanks in advantage,
