Robert - Please tone it down. Zed is aware of this thread and
perhaps even seeing this message. There is no need to resort to such
verbiage - Zed and I have been communicating and he is a fan of
Lucene and has proven in his last entry that Lucene is faster than
Ruby/Odeum even with the massive memory issue he notes (and has been
properly informed of what he's doing incorrectly in that situation).
Speaking for myself - I want the most accurate, flexible, and fastest
search system possible regardless of platform or language. Certainly
I want it to be Lucene, but I welcome competition and those that go
to the extensive effort of collecting data and making studies such as
Zed has. The Lucene community can help keep this type of competition
healthy and positive by educating folks in proper Lucene usage and
responding in kind regardless of the mistakes, attitudes, or flame-
bait we may encounter.

Here's a follow up:
http://www.zedshaw.com/projects/ruby_odeum/odeum_lucene_part2.html
Now the claim is that Lucene is faster than Ruby/Odeum but it
takes 36
times more memory. However, I cannot find any information on how
exactly
Lucene was started. It's no surprise that Java requires much memory
and
doesn't clean up if it never comes close to the limit set with -Xmx.
I went around several times in e-mail with Zed, the author of this
comparison after his follow-up. His paraphrasing of me in there is
only partially sort of what I said to him. He's instantiating an
IndexSearcher inside a tight loop which I told him was a very bad
thing to do with Lucene and that his loops are so tight that garbage
collection isn't getting a chance to kick in. He doesn't currently
believe some of this from me, and also feels that adjusting the code
to make Lucene happy is being unfair.
I wish the RubyLucene folks would hurry up and get a port over there
so that we could compare against Ruby/Odeum "fairly" :)
