[hibernate-dev] add a critically important notice to documentaion in Search

Hi Hardy, it seems we failed to properly warn users to use the new Solr packages you prepared [1]; I was going to open an issue for this to hopefully have it included in the release, but it seems I'm too late to mark it for the release of monday. Could you please reopen and add a warning in the docs before releasing it? I hope it's possible as it seems quite critical, otherwise please mention it in the release announcement. Thanks!
