Abstract — Next generation computing stared with the advent of Cloud computing. In cloud computing data possessor are goaded to farm out their complex data management systems from local sites to the commercial public cloud for great flexibility and economic savings. To ensure the safety of stored data, it becomes must to encrypt the data before storing. In cloud the data search arises only with the plain data. But it is essential to invoke search with the encrypted data also. The specialty of cloud data storage should allow copious keywords in a solitary query and results the data documents in the relevance order. This paper focuses on multi keyword search based on ranking over an encrypted cloud data (MRSE). The search uses the feature of similarity and inner product similarity matching. The experimental results show that the overhead in computation and communication are considerably low
