Hi,
We are working in a network of search websites here in Brazil called
www.sitedebusca.com the complete list are in
http://www.servicodebusca.com/sitesdebusca.php and we add some patchs on
search.jsp to show the results in a
simple XML format, to read in your own application actually write in PHP.
We already are using nutch in a "beta" environment. We have plans to use
only nutch on a network of more than
50 regional search web sites.
The code of search.jsp are in the next lines, i hope you can understand
my email and i hope this code are useful for
you.
Regards,
AtlasVision - Team

Subject: XML OUTPUT
Hi!
Does anybody knows how to output search results in XML format?
I would like to provide my data like Google/Yahoo do with their API's.
Thanks!
