i defined as follow to display mails in customer(res.partner) window <button name="%(mail.action_mail_archives_feeds)d" type="action" context="{'search_default_partner_ids': name }" string="inbox"/> <button name="%(mail.action_mail_archives_feeds)d" type="action" context="{'search_default_author_id': active_id }" string="outbox"/>

is there any possibility to pass '|' in context to combine both. i want both should be done in single button.
