Dear list, after going from 3.6 to 4.0 I see exceptions in my logs. It turned out that somehow the "q"-parameter was empty. With 3.6 the "q.alt" in the solrconfig.xml worked as fallback but now with 4.0 I get exceptions.
I use it like this: SolrParams params = req.getParams(); String q = params.get(CommonParams.Q).trim(); The exception is from the second line if "q" is empty. I can see "q.alt=*:*" in my defaults within params. So why is it not picking up "q.alt" if "q" is empty? Regards Bernd
