Hi Fred,
I think that we can help you if you provide us your code, and the
context in which it is used.
we need to see how you open and close the searcher and the reader, and
what operations are you doing on index.
All the best,

very correct you are. changing the format of the numbers when i index
then and when i do the range fixed my problem.. thanks much.

Fred,
I won't get into the details here, but you shouldn't (have to) open a
new IndexReader/Searcher on each request (I'll assume the code below is
from your Actions'e xecute method). You should cache and re-use
IndexReaders (and IndexSearchers). There may be a FAQ entry regarding
that, I'm not

That's right, there are many references to this kind of problems in the

Hello Fred,
When you recreate an index from the scratch (with the last
IndexWriter constructor's argument true), all IndexReaders must be
closed, cause IndexWriter tries to delete all files entire directory,
where you index being created.
If you have any opened IndexReader within this time, then

Hi,
I guess you have answered yourself. I can imagine that Tomcat was serving your
servlet with constructed index searcher while your command line application wanted to
recreate the index. Are you protected against this situation?

Hi everyone,
I am trying to use the Lucene + BDB integration from the sandbox
(http://cvs.apache.org/viewcvs.cgi/jakarta-lucene-sandbox/contributions/db/).
I installed C Berkeley DB 4.2.52 and I have the Lucene jar file.
I have an example program that indexes 4 small text files in a
directory
I used BDB + lucene successfully using the lucene 1.3 distribution,
but it broke in my application with the 1.4 distribution. The 1.4
dist uses a different file system by default, the cluster file
system, so maybe that is the source of the issues.
good luck,
