I'm not just responding to just you there, but more to the growing pack of those speaking against the new API. I don't see specific issues being brought up - the only issues I have seen brought up have been addressed in JIRA issues that have received no comments indicating the fix was not good enough. So we are seeing a lot of general complaints, but specific complaints have been addressed as far as I can tell.

Thanks Mark. Yeah, I'm really not sure what actually the problem here is now. There was a performance test in Solr that apparently ran much slower after upgrading to the new Lucene jar. This test is testing a rather uncommon scenario: very very short documents.

That is not an uncommon scenario. Solr has very, very short fields _ALL THE TIME_.


I meant that having documents that only contain very short fields is not as common as having docs with a decent amount of text. Maybe I'm wrong - in either case I didn't try to say it's not an important use case. I think it is important to have good performance here too. The point I was trying to make was that we tested performance more thoroughly for the case we thought would be more common.

According to the numbers posted on LUCENE-1796 it now seems like it's fixed - even for documents with only very short fields and no reusable TokenStreams.

 Michael
