You say the stack trace is null, does that mean you are getting an
NullPointerEx. or that you aren't getting any exception but the reader
is still null? Are you sure indexName isn't changing?
Also, it's not very good to open up the Searcher/Reader for every
query anyway, not that solves this problem.

Below is the related code in jsp file, and the stacktrace is null
even it failed to open the index.
try
{
out.print("To open index");
reader = IndexReader.open(indexName);
out.print("have opened the index");
indexsize=reader.numDocs();
searcher = new IndexSearcher(reader);
}
catch (Exception e)
{
e.printStackTrace();
error = true;
}
.....
if (reader != null)
reader.close();
if (searcher != null)
searcher.close();

Hi.
And some exception stacktrace would be nice as well.
Kindly

Xh,
Sorry about those questions. I received two copies of your email.
The first
was corrupt.
We still need to see more code. No there isn't any special config
necessary.

Subject: failed to open an indexer after about 20 queries
Hi,
The indexer can't be opened after about 20 queries in linux system,
but it
is fine if the index is in windows system. The indexer is the same
in both
systems.
reader = IndexReader.open(indexName); //failed after
about 20
queries
searcher = new IndexSearcher(reader);
The reader and search have been closed after each query. Is there any
special configuration for the index in linux system?
Appreicate your help very much.
BR,
Shawn
