However, because of the random and spontaneous joining of the nodes and the lack of centralized system management in the distributed P2P system, some urgent problems regarding the availability and security of P2P network remain to be solved.

The file sharing systems based on Peer-to-Peer architecture are being rapid and wide-spread on the Internet. Unfortunately, most of the current structured P2P systems which have not any central server can not support the keywords-based retrieval.

P2P模式的文件共享系统在Internet上得到广泛应用，但在无中央服务器的纯P2P文件共享系统中，多关键词检索问题还没有得到很好解决。
