I read here http://lemurproject.org/clueweb09/ that there is a hosted version of ClueWeb09 (the latest is ClueWeb12, for which I don't find a hosted version), and to get access to it, someone from the ASF will need to sign an Organizational Agreement with them as well as each individual in the project will need to sign an Individual Agreement (retained by the ASF). Perhaps this can be available only to committers.
Though, we need to get access to ClueWeb12 if we want to publish Lucene results on the latest data set. TREC papers are already based on that version. But if we just want to measure performance, relevancy etc., ClueWeb09 could be a good start.
