How to trigger a rebuild of nepomuk email database

Is there a way to dump my previous email feed to nepomuk and ask it to build 
it again?

Here on a fresh import in a fresh install of kubuntu 11.10 updated to KDE 
4.7.3, somehow the nepomuk database seems corrupted. The message previews are 
mixed up and show some other mail from even a differrent account.

Ps: Does the nepomuk database ever shrink? ie. if i delete some mail or even 
an account, will nepomuk "forget" all about it?
