FILTER FOR A DISTRIBUTED NETWORK

摘要

A filter for a distributed network may include receiving index requests from indexing nodes over a network and providing over the network index responses to the indexing nodes in response to the index requests. The index responses may instruct a receiving indexing node to index or not index a specified file. The method may be implemented in software and executed on a computer.
