Possible Bug with MultiSearcher?

Sep 2, 2002, 10:13 AM

Post #1 of 3 (278 views)

Hello,
I am getting the following exception when searching using a
MultiSearcher and the first Searchable added is an empty IndexSearcher
with a segments file, the second is a normal IndexSearcher from a
populated Index . I am able to reproduce this without fail. The
exception is thrown when trying to retrieve a document from the Hits. Is
the exception really waranted, given there are hits in the second index,
I don't think the search should fail completely? When searching an
individual index, adding it to a Multisearcher, and performing the
search causes no problems. Any help or suggestions would be appreciated.

Please see org.apache.lucene.store.InputStream.java 192:46 for the
location where the Exception is generated.

Can you please submit a complete, self-contained test program that
demonstrates the problem? That will make it much easier for someone to
debug and fix it.

Thanks,

Lucene Developers,
A test program is attached. I reiterate that the searcher for the empty
index must be added first. The exception thrown at the end of the
program is an ArrayIndexOutOfBoundsException. I will continue trying to
recreate the orginal exception which I reported, but I think this one
may be related. I was unable to recreate the exception using
RAMDirectory stores, but only two FSDirectory stores. It maybe necessary
to delete these directories from time to time???? Please let me know if
I can provide any more information.
