[Pki-users] How to find private key by owner certificate?

Hello Dogtag users. Maybe You know how to find private key by owner certificate? On user side it can be done in data recovery manager -> search for keys -> show the key that corresponds to the following certificate. I download dogtag sources but all I found is some query building and resend it to this same page but I can't find where exactly this arguments are parsed and used for filtering results. KeyClient has only method called listKeys(type,state,max,size,time)(not sure about order) but I can't find method which takes more specific arguments. When I list all keys in drm, none of them have publicKey(so my idea to get public key from cert and looking for same key in all key list is not possible). Any ideas? It can be done within console interface? I tried with pki key-find but that doesnt work.
