Private profile fields are displayed in search if Profile Privacy module is used in combination

The problem is that the profileplus module (or any module that searches through user profiles) looks at the privacy values in the 'profile_fields' table and not the 'profile_privacy_values' table.

the search code is the following (for users that do not have 'user admin' privileges)

 $sql = "FROM {users} u INNER JOIN {profile_values} pv ON u.uid = pv.uid INNER JOIN {profile_fields} pf ON pv.fid = pf.fid WHERE pv.value LIKE '%%%s%%' OR u.name LIKE '%%%s%%' AND pf.visibility IN (%d, %d) AND u.status = 1";
              $result = db_query('SELECT DISTINCT u.* '.$sql, $keywords[$j], $keywords[$j], PROFILE_PUBLIC, PROFILE_PUBLIC_LISTINGS);

I'm really bad with sql - do you have any ideas how I could join the tables or whatever to filter out fields for the users that declared them private? :D

thanks!

UPDATE:
This is the code that I used - seems to work:

$sql = "FROM {users} u INNER JOIN {profile_values} pv ON u.uid = pv.uid INNER JOIN {profile_fields} pf ON pv.fid = pf.fid LEFT OUTER JOIN {profile_privacy_values} ppv ON pv.fid = ppv.fid WHERE (ppv.private IS NULL OR (ppv.private=0 AND pv.uid=ppv.uid) OR (ppv.private=1 AND pv.uid!=ppv.uid)) AND (pv.value LIKE '%%%s%%' OR u.name LIKE '%%%s%%') AND (pf.visibility IN (%d, %d)) AND (u.status = 1)";
              $result = db_query('SELECT DISTINCT u.uid, u.name, u.mail, pf.fid, pf.title, pv.value '.$sql, $keywords[$j], $keywords[$j], PROFILE_PUBLIC, PROFILE_PUBLIC_LISTINGS);
