I am running Python2.4 and PyLucene Version 2.0.0. I have a folder containing
several text files. I successfully run IndexFiles.py form the Python sample
files folder. However, when I attempt to run SearchFiles.py, I get the
following error message:

TypeError: descriptor 'parse' requires a 'PyLucene.QueryParser' object but

The same procedure worked without any problem on PyLucene 1.9, the error has
only arisen after the upgrade. (I installed the new PyLucene 2.0.0, and am
using the PyLucene 2.0.0 sample files
This is a known and fixed bug. Get the latest PyLucene.
I attached the latest SearchFiles.py or get it from [1]

This script is loosely based on the Lucene (java implementation) demo class
org.apache.lucene.demo.SearchFiles. It will prompt for a search query, then it
will search the Lucene index in the current directory called 'index' for the
search query entered against the 'contents' field. It will then display the
'path' and 'name' fields for each of the hits it finds in the index. Note that
search.close() is currently commented out because it causes a stack overflow in
some cases.
