Re: reoot site query results
In web search, link information helps greatly. (This was Google's big discovery.) There are lots more links that point to http://www.slashdot.org/ than to http://www.slashdot.org/xxx/yyy, and many (if not most) of these links have the term "slashdot", while links to http://www.slashdot.org/xxx/yyy are somewhat less likely to contain the term "slashdot". As Erik hinted, Nutch uses this information. It keeps has a database of links that point to each page, indexes their anchor text along with the page, and boosts highly linked pages more than lesser linked pages.

Re: reoot site query results
Perhaps look at Nutch to see whether (and if so, how) it deals with this situation. Determining the root seems to be a pretty tricky endeavor. Each of these could be a root: http://www.ehatchersolutions.com/JavaDevWithAnt http://www.example.com/~username And certainly lots of other combinations like you've described.

Too must of a boost might make it return higher than perhaps a non-root page which is more relevant.
