Hi, I’ve an application which is built with RoR and a search index in Lucene. I need to be able to integrate Lucene into the RoR app. What is the best way to do so ? I know that rjni is a ruby-java bridge but is it stable ? Also the update at [http://thekode.net/ruby/rjni/](http://thekode.net/ruby/rjni/) seems to indicate that it is no longer under development. Thanks. Ruban. ---

Hi, Ruban, as just posted in another thread: Have a look at ferret ([http://ferret.davebalmain.com](http://ferret.davebalmain.com)), which is a full ruby port of lucene. You’ll find performance comparisons on [http://blog.davebalmain.com](http://blog.davebalmain.com). Dave is doing a great job!!! Also the article [O'Reilly Media - Technology and Business Training](http://www.oreillynet.com/pub/wlg/8168) might interest you. regards Jan P. ---

Just actually read a bit about Lucene, and found that there is a new port called Ferret which you may find interesting. Might be a more effective shift to move from Lucene to Ferrett then build a Ferrett gem to integrate into Rails. I am sure this would be well received open project in the Rails community 🙂 Warmest regards, Nathan. * * * Nathaniel S. H.

Thanks Nathan and Jan for the info about Ferret. This definitely looks promising. But the problem is that the Lucene index is used by various other applications and is generated by a different application. I just read from it and so I can’t really move the index to Ferret. But if I have to create one myself Ferret would definitely be in one of my preferences. Ruban Phukan ---

Thanks everyone. These were all very useful info … sorry for overlooking the “full port” part of Ferret earlier. Ferret rocks… eagerly waiting for the high speed C extensions. Ruban Phukan ---

Have the developers considered using RubyInline to optimize Ferret? That might be better than writing a C module. ---

Ferret can read indexes generated by Lucene. See “How to use Ferret on an Existing Java Lucene Index” on [http://ferret.davebalmain.com/trac/wiki/HowTos](http://ferret.davebalmain.com/trac/wiki/HowTos) . By “full port”, it means the whole enchilada is there, fully (?) compatible with Lucene. Actually, once the snazzy new C extensions are integrated, I’ll be faster than the original Lucene. Now isn’t that just peachy? Jacob
