I was following this book to install the ZendSearh on the application, I did exactly as it's written and I'm getting a Fatal error: Class 'ZendSearch\Lucene\Lucene' not found in /var/www/CommunicationApp/module/Users/src/Users/Controller/SearchController.php on line 107

It has its own repository on github.
https://github.com/zendframework/ZendSearch
You have to load it via composer or just download and put it under vendor folder.
