Keyword search is an important aspect in p2p systems. Some key search methods for structured p2p systems use hypercube as a logic keyword search layer. However, the search is inefficient when query keyword set is small. In this paper, this weakness is addressed by replacing hypercube with a modified Cube-Connected-Cycle (MCCC). A better index and search scheme based on MCCC is proposed.lt is demonstrated by experiments and analysis that the search scheme works more efficiently under a MCCC when the number of query keywords is small.
