How to get all documents (i.e Excel Sheet only) related to a particular party in Zoho Mail?

Like I chose at search box->Attachments-> that contain->[party name] {that includes only excel files}

and alternatively i marked as favourite and want to access all favourite marked docs which are not found i.e The Favourite Folder so that i can download all the files that i marked favourite

so, kindly help ASAP!
