This is a bug in the query-basic plugin. The boosting values in the
nutch-default.xml are not used.
We should open a bug in jira. This simple patch should work.

Hi,
I was experiencing a "strange" selection of search-results here. The
first idea was to rate the results with searchword in hostname higher.
So I set query.host.boost to quite a high value (50, later 200). But
nothing in the result changes.
Searching for the full hostname (www.example.com) does not give me any
search at all. Could it be that hostname is not taken into account
during a search?
What could be wrong here? Please help. *sigh*
Thanks a lot,
Stefan
