Adding configurability is good, and also changing the default value to be bit more optimal would be even better? Just changing default to 2k or 4k (4k is close to a physical page size, might be good default?) might be worth doing as well. I mean, 90% of users probably use things exactly as they are configured by default; so this would probably make many Lucene users happy. ;-) -+ Tatu +- __________________________________________________ Do You Yahoo!?
