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.
Each indexed field adds a file per segment. So, if you want to conserve file handles, use fewer indexed fields per index, and/or use multiple indexes, as you have done.
