I am not interested in any specific document, but just only in
everything related that is publicated for the public and linked
accordingly on the website of KDE and the webpages of Baloo.

<div>We have been evaluating both 'lucene++'
(lucene branch) and writing our own engine
on top of 'lmdb', which is key-value store.
(feature/vhanda/lmdb). Currently, I'm
leaning more towards lmdb, as it gives us
way more control over the entire system. But
I still have to perform comprehensive
