In this paper, the authors propose multi-user searchable encryption with the help of order preserve encryption for providing efficient encrypted data. when proposed these constructions it formally defines the multiuser settings for ranked keyword search by using searchable symmetric encryption and order preserve symmetric encryption. Consider a data owner is the administrator who can uploads the files before encrypted into the outsourced cloud server. These files are encrypted in the cloud server which can be shown as an index file for users.
