Correct, there was no plan for such operation yet. It can sure be a =
useful thing.
I wonder if there's a lot of literature about such best practice btw.=20
This I would be very interested to hear.

I think that one of the keys here is that we would need external =

It sure is desirable but the toolset was not right-away available for =
this.

The simple log counts as Fran=E7ois Schiettecatte just responded in the =
solr list would even be useful but again, it needs a little extra =
programming.

All people I met would recommend Google Analytics for this. I tend to =

solutions. Hence I made this thread public to hear about "satelites" =
(which are somewhat lucene related).
