You can store the fields in the index itself if you want, without indexing them (just flag it as stored/unindexed). I believe storing fields should not incur the "norms" size problem, please correct me if I'm wrong.

If not, you probably don't have to index these fields (but store them for retrieval?). Just a thought.

I think you'd need to test different values for your situation. Maybe try 66,000 which will give you ~ 10 segments at your current number of docs? > I have the searching result in 30 to 3 minutes, which is actually quite > unacceptable for the "search engine" I build...Is there any > recommendation on how faster searching could be done? I think you'll need to turn off norms. I expect alot of the slowness is in loading the large norms files for the first time.
