That completely depends on how you model the queries. It can be a TB sized relation all the way into needing more bits than there are atoms on the universe.

This is not a generic discussion, we are discussing web search IR in particular, but if you want to be pedantic, the TB sized dataset could be the PageRank values and "scoring" could be the ordering of these values.

The TB dataset is PageRank indexed by search term. You can correlate them more and more and end up with exponentially more data, but even the smallest one (that you'll need a hack of servers to query) is quite useful already.
