Cloud computing is considered as a utility which allows the users to store their data on to the cloud servers and therefore allow data access to the users through the servers. This uploaded data to the cloud contains privacy information and hence this leads to the necessity of encrypting the data before they are outsourced to the servers. This leads to difficulty of searching since the data is encrypted and to solve this issue searchable encryption is introduced. The objectives of this paper are: First, to introduce the preference and relevance factors in order to enable best keyword search and to improve user experience. Second, to apply logic operations of the keywords which are AND, OR and NO operations. Third, to achieve better search efficiency by building index using sub-dictionary technique. The document or the data retrieved using the keywords can later be downloaded using the key which will be provided by the data owner through email.
