Just use 1.5 if you can. I've been using it for months on simpy.com
along with Lucene 1.9 and haven't had any problems so far.

Xin,
Look for a Lucene-based spell checked in Lucene's contrib directory (in
SVN).

Thanks. I will take a look at those classes.
I do need to support search queries like:
- Find all files that are named foo.doc.
- Find all the files that have not been accessed in last 6
months(atime).
- Find all PDF files with size > 2 MB
The HW requirements are flexible in terms of memory and CP

Hi,
I am looking at Lucene to index and search file metadata - filename,
size, permissions, mtime, ctime, atime, etc.
I do not need to index and search the contents of the file. I was
wondering if Lucene is the right choice for such an application. This
will be at enterprise level so there could
Place the lucene jar file in the WEB-INF/lib directory of your web
application prior to creating its war.
If your ISP inspects the war and removes all jar files within it, then I
suppose you might just have to place all the lucene classes under
WEB-INF/classes of your web application as 'loose cla
Anyone plug-in a spell checker into lucene to implement google-like function
"do you mean .?" for wrong spelled word or phrase?
Also, which spell checker product is good?

Hello,
My provider only allows to upload war files. My problem is I make a war
archive out of the lucene-1.4.3.jar file and my jsp webpages based on
lucene. And this does not work. I hava one solution to solve my problem:
I have to unpack the lucene-1.4.3.jar file and pack it again with my

I have downloaded Lucene 1.4.3
I am trying to narrow down on the JRE version to use.
We have the flexibility to use 1.3.1 up.
Which JVM will be the best for running Lucene?
I saw a note on the FAQ that said that Lucene will run on 1.3.1 but will
require 1.4 to compile.

Not sure if this is feasible, but is there someway you could use a

then have it output the tokens directly from the hashtable via the

No code, but some small thinking. You can do hacks with boosts and

I've some thoughts about Lucene and Relevance Feedback. I want to

The formula is like this:
