ranking works in topN selection?

I have some questions.

1. What is the ranking algorithm for Nutch?

2. Does this ranking algorithm come into play, when at a certain crawl
depth, Nutch is confronted with 10000 possible URLs but the topN value
is only 100.

3. When exactly is the topN selection done? Generation? Fetch? which phase?
