I'd like to, using Google Search, get a complete list of all the blog URLs that are hosted under specific domains. You know, like "[blog].wordpress.com", "[blog].blogspot.[any]" "[blog].blogs.sapo.pt", and the like.
Let's consider ".blog.sapo.pt". For
* site:blogs.sapo.pt, I need to get rid of every result that has a
path after the domain, that is,
-inurl:/ . But Google disconsider characters like
/, so it's more complex.
Is there a way to search the way I need using Google? If it's possible, how to do it?
I don't want to need to resort to a DoS-like method of "brute-checking".
