Roundcube search() function - Search criteria provided by array missing

[Cuiry]

Hello,

I'd like to kindly ask you if there is a chance that this TODO will be fullfiled?
TODO: Search criteria should be provided in non-IMAP format, eg. array
It is located in these files:
lib/Roundcube/rcube_imap.php
lib/Roundcube/rcube_storage.php
$str parameter is String and I'd really need that I can input Array as a parameter and it's going to filter emails according to the array values.

Thanks in advance for your reply.
