ZF1 had a gread search lucene implementation. is there something similar for ZF2? I can't find anything...
It is part of ZendSearch and you'll find it here https://github.com/zendframework/ZendSearch
If you drill down through the folders you'll find Lucene, but you'll probably need to install the whole thing following the instructions in the readme file on the first page I linked to.
Alternatively you can cd into your vendor directory and run:-
git clone https://github.com/zendframework/ZendSearch.git
That will create the ZendSearch module and you can then add it to your modules list in application.config.php
Also see the Zend Framework package repository.
