You could start a strigidaemon on its own, but then you don't have Nepomuk integration. This got disabled in 4.2 because the performance of Strigi with Redland as storage always was an absolute nightmare and some internal changes in 4.2 made it even worse. I think the way they disabled it needs fixing (there should be a way to enable it - they just hardcoded the disabling), but to be honest I wouldn't really recommend enabling it even if there was a (working) option. (But if you really want to try, I can provide patched packages with the disabling logic removed somehow.) Strigi is said to be very fast with appropriate storage (such as its internal CLucene storage, but that one doesn't integrate with Nepomuk), but with the slow Redland it's a PITA. * the new nepomuksearch:/ ioslave in KDE 4.2. (I think this one is not actually explicitly disabled, it just plain does not work due to missing features in Redland.) What is enabled: * compiling all the stuff, so plugging in a soprano-backend-sesame2 (or soprano-backend-virtuoso when available) at runtime will enable all the above, and * you can store tags even with the Redland backend and they will be kept inside the Redland storage. Without search, this is not all that useful though. Kevin Kofler
