Searchable encryption is crucial for the encrypted data utilization, especially in the database generated by multiple owners. Many existing schemes support single keyword query, and assume that the search users are authorized and the returned results are correct. However, single keyword query wastes network bandwidth
Encryption (SSE) to facilitate keyword-based searches on the ciphertexts.
