Yes thank you very much sixcooler for this advice! It works quite fine, and I think it will be very useful for every day searches!
Personally to have a true host name search behavior I had to apply quite extreme settings :
- host_s and host_organization_s boosted with value : 50.0
- only kept fields title, author and description_txt
I believe such a common use case should have a pre-configured profile as it is done for "Date profile".
At least wiki page http://www.yacy-websearch.net/wiki/index.php/En:Ranking
could be more detailed for this case.
