Hi Eric, Thanks for your reply.
I verified Srinivas' query by changing Lucene version ( in the constructor of StandardAnalyzer ) to LUCENE_30 to find that parsed query indeed changes to xyz abc (input query was 'xyz_abc') while that does not happen in case of LUCENE_33 and the parsed query remains 'xyz_abc'. I can't figure out why that may be happening. Regards, Govind On Mon, Aug 22, 2011 at 7:22 PM, Erick Erickson <erickerick...@gmail.com>wrote: > No, that's expected.
