--------------------------------------

Hi Julien, thanks for this patch...
is there any way to inherit the metadata or parts of it to suburls while crawling? 
I fiddled around with a scoring filter but with no success.

Cheers
Claus

> the patch attached allows to inject metadata into the crawlDB. The input file has to contain fields separated by tabs, with the URL being on the first column. The metadata names and values are separated by '='. A input line might look like this:
> http://www.myurl.com  \t  categ=value1 \t categ2=value2
> This functionality can be useful to store external knowledge and index it with a custom plugin
