I have no real use for nepomuk which has been a plague on KDE. Recoll just works nicely niced in the background, none of the problems. Find my runner for using recoll on kde-apps site.


Unfortunately, it is now not possible to search messages within kmail without Nepomuk. Want find in message, find messages, etc., we're stuck with Nepomuk.


Even without neomuk, kmail is a mess, however.
