Using Luke?

Hello all,

Has anyone been using Luke to examine index generated by
PyLucene?
I'd like to use Luke to debug my search but I always get a
"invalid path, or not a Lucene index" error from
Luke when I point
it to the index directory.

Best regards,
Jack

Make sure the Lucene jar Luke is using is the same as the
one  
PyLucene is using. On my system I have to call luke by:

java -classpath luke.jar:lucene-core-2.0.0-478273.jar  
org.getopt.luke.Luke

A Lucene index created with PyLucene should be the same byte
for byte as an 
index created with Java Lucene. If that is not the case,
please send in code 
to reproduce the error, it's a bug.

I've never used Luke myself so I can't tell what the error
is about. Maybe the 
version of Luke is not compatible with the version of
Lucene/PyLucene you're 
using ? There have been index format changes in Lucene 2.0.

Thanks Andi and Brian for the reply. I'm still getting the
error.
Here's what I did:

I downloaded lucene 2.0 from a mirrow link
http://download.nextag.com/apache/lucene/java
/lucene-core-2.0.0.jar

And here's how I run luke:
java -classpath luke.jar;lucene-core-2.0.0.jar
org.getopt.luke.Luke

I run Luke and navigate to the directory generated by, which
is:
PyLucene-2.0.0-8samplesLuceneInActionindex

Luke still complains that it's not a lucene index.

I'm not sure that the formats between Lucene 2.0.0 and
PyLucene 2.0.0-8 are 
exactly the same. PyLucene 2.0.0-8 is built from a recent
Java Lucene trunk 
snapshot. To be sure, download the PyLucene 2.0.0-8 source
tarball and use the 
Lucene JAR file to be found in there with Luke.

Thanks. This fixed it. I didn't know that the file format
in Lucene changes all the time!
