is there any way to prune webdb?

[Gal Nitzan]

Hi,

Few questions:
1. Is there any way to remove/prune unwanted url from webdb without 
deleting all webdb and than updatedb?

2. After using prune, must I use updatedb to update the webdb

3. Is there a way to remove unwanted records from fetchlist ?

4. Does generate use regex-urlfilter in the process?

5. I noticed fetcher fetches pages in the fetchlist though it should not 
because of a rule in the regex-urlfilter how come?

Thanks,

Gal
