Subject Re[2]: Seeking suggestions - keyword related site promotion
Date Thu, 19 Jun 2008 08:23:01 GMT
Hello Stephen,

I'm trying to understand what you are suggesting.
Yes, I have a fixed set of keywords for each "good" site,
although they occasionally get edited.

Not sure what you mean by "index these keywords into
a field for each site". Did you mean index these keywords
for all pages (that contain those keywords) of each site?
So that I can boost the field weight in dismax query in
order to boost these sites? I think this is a way of
doing this. Problem the right way. The downside is that
when I need to edit the keyword list, I'll need to
re-index all pages that contain those keywords. But there's
probably no easy way around it.

As far as I know, Nutch doesn't do site specific boost.

Thanks,
Jack
