Baloo ist basically Spotlight and probably more but dare you are not that typical happy smile buisness user - have a few kernel source tree's laying around in your /home and you'll likely are getting friends with Baloo sooner (spinning rust) or later (ssd) because that beast manages to saturate even SSD IOPs and while doing so hands out segfaults on every other file. You can switch to disable content-indexing and just search for filenames (80% rule) but it's hidden in systemsettings or you even need to go to balooctl - also index corruption is a thing... That beeing said, if you are a brave KDE user and don't mind the hassle it might even work 80% of the time - in theory it's great idea but it never worked reliable for me - if you are a bored dev there is probably lot's of low hanging fruit there - seccomb, some simple heuristic to not overload on IOPs, there are probably more efficient db structures than LevelDB and so on... It's step forward from nepomuk? that did the full rdf semenatic web stuff and fed a relational database and killed your hdd-based desktop reliable in the early 2000ies but it's still a nasty surprise when using KDE. It's still a cool idea but it needs some love and contributors to work reliable on all kinds of nasty setups.
