Hi everybody,
which kind of retrieval model is lucene using? Is it a simple vector model,
a extended boolean model or another model? A reliable source with
information about it would be fine, cause every source i found is telling
something different. :)

Hi,
I modified the analyzer (it is now vegetarian and won't eat numbers anymore
:-) but I have hit a new problem. The parser won't accept a keyword to start
with a wildcard character. (*/12/2003) Any hints to solve this new issue?
Many thanks
Chris

Hello,
As i also encountered the phrase query issue with the old highlighter
code, I added a fieldName argument in case of the analyser handle it in the
tokenStream() method.
I just submitted the patch on bugzilla

Hi -
I tried increasing SUMMARY_LENGTH to 1 (originally 200) in HTMLParser.java
and HTMLParser.jj files. The purpose is to create snippet and highlight the
search terms within it.
Then I used ant to compile (also used javacc-HTMLParser, compile, jar,
jar-demo, war-demo and copied war file
A couple of sanity checks... you changes the main lines, not the
comments I hope :) And also, you need to rebuild the parser code by
running JavaCC on it. If you're tinkering with a copy of Lucene's
source code you can run the Ant target "javacc" and you must have
JavaCC installed per the
Well, I guess Lucene's Span query uses the Cover Density based model
(proximity model). However, it is within the framework of the TF*IDF
as well.

Hello,
Looking for most useful lucene taglib and have found references to one written
by a Iskandar Salim found at www.javaxp.net/lucene-taglib, but that site is
404. Found a patch submited in 2003 bug# 20283. Downloaded and seems adequate,
but from the docs I've read, the javaxp seems superio
Chris,
Once upon a time there was a taglib area in the Lucene Sandbox, but
that has since been removed since the contributor of it disappeared.
What do you need a Lucene taglib to do? I personally thing such a
taglib is overkill and harder to use than it would be to just code up
the func
I was following an example in a book that referenced that taglib :) Book's
copyrighted 2004 so there may be at least a small user base out there. I
finally got the Sandbox version to work correctly on lucene 1.2. It doesn't
work on 1.4.x.
Perhaps it may be an overkill of a taglib, but my fami
:-) I changed the main lines and compiled the QueryParser.java after that I
compiled the entire package, build a new jar file and installed it on my
server. (I followed the same procedure I used when I added a new analyzer)
Cheers
