Hi. Not very problematic, but probably somebody has run into same.
After download last community build, ezfind is not activated by default. Anyway, as i have other installs in my dev machine, solr was properly running.

Trying to start indexing process before activating the extension outputs an error that may confuse somebody. error looks like

The Solr server couldn't be reached.
Please, ensure the server is started and the configuration of eZ Find is correct.

In my case, i double-checked my solr and my ezfind files (included with the distro) but didn't realized i haven't activated it

I think it would be nice to check if ezfind is activated and if not, exit there showing a nice message remembering the user to do that.
Thoughts?

Steps to reproduce

Install a fresh last community build
be sure you have solr running
start index processing

other way to check is just deactivating ezfind and try to start the index process.
