Deleting indexed items

[Paul Wellner Bou <paul purecodes org>]

Hello,

I just wanted to know if there is any way to delete items that are 
indexed by beagle. For example mails that are deleted yet or websites I 
visited with Firefox or Opera and I don't want them to be in the index.

I have no problem with files as beagle seems to recognize it almost 
immediately if I delete a file. I don't know how beagle handles the 
Feed-Entries. How long are they stored in the index? As long as my 
newsreader keeps them?

Thank you very much.
Regards,
Paul.
