Hi, I am bumping up this thread to see if there are any further inputs on this. I was planning on running a benchmarking test for .NET vs Java for both Indexing & Querying (single field, multi field, span etc.), and would be happy to share my results. I would be using the PubMed corpus of biomedical literature and running indexing on a few million articles.
I would be interested to see if others are running on other corpora, sharing ideas would be very helpful IMHO.
