Subject Re: Lucene Java Vs .Net
Date Thu, 14 May 2009 00:52:44 GMT
I am running all tests on the same box - a Windows workstation.

Granted the comparison might not quite be apples vs apples in a true
scientific sense, at least it would be slightly more scientific  than
some of the anecdotal information shared by some here.

so perhaps green apples vs red apples :-)
