I am evaluating SS for use as an enterprise intranet and one of the functional requirements is a search facility that will cover document formats such as PDF, Word and Excel.

I was pleased to find the Zend_Lucene module already in existence here: https://code.google.com/p/lucene-silverstripe-plugin/

However this, and everything else I find in searching Google and Silverstripe suggest that this module is only supported by Silverstripe 2.4.

There is a link on the above page to a github repo of a Silverstripe 3 port of the plugin. However this link is broken. And search results net nothing.

Is anyone aware of existing Lucene support, if any, for SS3?

For future reference, and I haven't tested this yet, but the git repo for the SS3 port simply changed.

that module is buggy. takes me quite a while to set it up. it's not a public git so i can't contribute :-(

Building ontop of the Zend Lucene library is a pretty straightforward. In docsviewer (3.1) we use Lucene as the engine without using the module, I guess the module would provide a better facade to handle some of the boilerplate.

Two parts we use for documentation indexing:
