I'm trying to develop an interface to roundcube and would like to pass it a search query for a specific folder.

Does anyone know a proper way to do this over a HTTP GET request?

I've tried these queries after viewing the headers during the AJAX search query (*string* is the URL encoded search query):

https://roundcube/?_task=mail&_mbox=Archive&_action=search&_q=*s...

https://roundcube/?_task=mail&_filter=ALL&_q=*string*&_mbox=Arch...

Neither proved successful.

Any throughts?
