This document proposes a new efficient solitude securing ranked keyword search technique for cloud computing. It presents a Multi-keyword Ranked Search over Encrypted Hierarchical Clustering Index (MRSE-HCI) architecture that uses quality hierarchical clustering to organize documents and support fast keyword searches in an encrypted cloud environment. The technique uses a minimum hash subtree to verify the correctness and freshness of search results to address integrity and security issues. Experimental results demonstrate that the proposed technique improves search efficiency, accuracy, and rank privacy compared to traditional methods.
