RAMDirectory is indeed currently limited to 2GB. This would not be too
hard to fix. Please file a bug report. Better yet, attach a patch.
I assume you're running a 64bit JVM. If so, then MMapDirectory might
also work well for you.

Hi all,
If I want to embed the index files into another file (say of

can I still use the index without having to extract out the index files to a

For example,

Hi Nikhil
We are using the index accessor contribution. For more information see:

This should help you to co-ordinate the IndexSearcher and IndexWriter.

How does the information change in each of these customer's documents?
I would think if they were very dynamic then updates to the single index
would not be great for you. But if the updates were just now and then,
then given the performance of lucene that the single index would be just
fine.

It seems the best way would be not have a separate daemon for indexing
