FYI: The best thing I've found for both increasing speed and reducing file handles is to use an IndexWriter on a RamDirectory for indexing and then use FileWriter.addIndexes() to write the result to disk. This is subject to the amount of memory you have available, of course...I do follow this strategy and it seems to work nicely... however it might be not enough :-( Another factor to consider is how homogeneous are your indexes: the more documents are alike the better. I tried a wide spectrum of combination and I settled on using one index per class of documents. This seems to work best for me as far as file handles go. YMMV.
Also, using addIndexes() progressively slow down the application to a crawl as the indexes to merge are continuously growing in size... Oh, well...
In any case, I also wanted to emphasize that I really do like Lucene. Thanks to all the people who contributed their time and effort to make this outstanding library. And special thanks to Doug for his clean and lean design :-)
Cheers,
PA.
