MergeErrors and things that has nothing to do with the code.

[liling tan <al...@gmail.com>]

Dear Fellow pylucene dev,

I've been using lucene (java v.3.0.1) without problems and my new project
group requires me to code in python. So i've some questions about
writers/readers/searchers/directories not closing after calling them to
close.

My problem is with MergeError when indexing large chunks of data, more
details could be found here.
http://stackoverflow.com/questions/14313568/how-to-resolve-mergeexception-from-massive-lucene-index-writing

I've tried the same code on 3 machines:
a) my server gives the MergeError as described in
http://stackoverflow.com/questions/14313568/how-to-resolve-mergeexception-from-massive-lucene-index-writing
b) my laptop, works fine but my RAM burns out and shuts the laptop down.
c) desktop, i've installed pylucene 2.3 with the same procedures as my
laptop from (
http://freethreads.wordpress.com/2012/07/22/pylucene-installation-on-ubuntu-12-04/
)
   but it gives
terminate called after throwing an instance of 'JCCEnv::exception'
Aborted


Is there anyway to resolve this problem? i've tried the suggestions given
on stackoverflow but it gets stuck at the same point.

Version 2.3 is years old. Please use version 3.6.2 to get all Lucene and PyLucene improvements and fixes that happened since then.

How so ?
What action did you take (based on the answers on stackoverflow) ? And what happened ?

If you keep track of all of them, sure. You're opening them, after all.
You might want to ask on the java-user@lucene.apache.org too.
