Porter stemmer is not only agressive, it is ugly, too. The generated
code is too old, too few object centric and should be too slow.
If your kstem compile with java 1.4, why don't you suggest it to lucene
core?

I know that only one query of that type does not change anything. But

My docs have Title and Description. What I want to do is to give

No, the MLT feature does not have that kind of field-specific
boosting capability. It sounds like it could be a useful enhancement
though. Of course you do get boosts for interesting terms already,
but maybe having an additional field-specific boost would be a nice
touch too.
It should help to weight the terms with their frequency in the
original document. That will distinguish between two documents
with the same terms, but different focus.

Hi Wagner,
Thanks for the intro of KStem! I quickly scanned the original paper on
KStem by Robert Krovetz but could not find any timing comparison data on
KStem and Porter stem. I wonder how slow/fast Kstem is compared to
Porter stem based on your use in your application?

Wagner,Harry
Hi Jay,
I did not do a timing comparison either, but any change in performance after
switching to Kstem was not noticeable. Cheers... h

I'm (still) seeking more advice on this deployment issue which is to use
org.apache.log4j instead of java.util.logging. I'm not seeking re-starting

a way to bridge jul to log4j with the minimum specific per-container

I actually doubt Porter's is slow. From what I recall, it's a bunch of simple
if/elses.
KStem can't get added to Lucene core due to its license (search Lucene JIRA for
an issue that covered this several years ago).

I'm using the Spellchecker handler but am a little confused. The docs say to
run the cmd=rebuild when building the first time. Do I need to supply a q
param with that cmd=rebuild? The examples show a url with the q param set
while rebuilding, but the main section on the cmd param doesn't say much
