As zeitgeist is used by Gnome 3 and Unity for tracking opened files it would be a great enhancement if recoll can notify zeitgeist about file open actions. ATM files which I have opened from recoll search results are not listed in zeitgeist journal and due to this not in the Ubuntu Unity file lens (11.10).

Release 1.17.0 has code to create zeitgeist events, but it’s not compiled-in by default because this was done to late before the release (needs more testing). You can enable it by building Recoll from source. You will need to use a --with-qzeitgeist option to configure (and --prefix=/usr presumably), and also install libqtzeitgeist.
