[Lucene.Net] Multiple IndexWriter will gain better build performance?

[Floyd Wu <fl...@gmail.com>]

Hi There,

I'm doing an offline index build process. Currently the final index
files is 2GB. I wonder if I divide this to 500MB each and create 4
IndexWriter to build 1/4 each.
Then doing a merge by using addIndex() to merge them into a final
index. Do I gain better performance(total time cost reduce)
theoretically?

Note, the each IndexWriter will be a thread in my application.

Please share your thought, thanks.
