One other thing to note, you can definitely see Lucene in action (or Nutch, that is) by clicking on the score returned for a given document (try searching for Lucene) and you see, in all it's glory, the Lucene explain results... It even displays the Nutch logo, which makes me wonder if they are misusing an ASF trademark (but, IANAL, so I don't know) since they don't state that Nutch is a trademark of the ASF. But, that is a discussion for somewhere else...

Hi,

I noticed that Wikia search goes live today (see
http://www.devxnews.com/article.php/3719906).
Does anybody know where I could find more technical information about their
solution? Are they going to contribute their enhancements back to
Lucene/Nutch/Hadoop code? My understanding is that as long as they claim they want to build their solution on top of open source technology they
should be contributing back.

Not sure what they have done, but nothing in the Apache license requires contribution back, even if it would be appreciated.

Cheers,
Grant
