A little background: I originally conceived of query operation chains (based on some of my previous hacking in mechanical investing stock screens: select all stocks; take top 10% lowest PE; then take the top 20 highest growth rate; then sort descending by 13 week relative strength).
So, I thought that the next thing after a query *might* be a sort, so getSort() shouldn't throw an exception if it wasn't. I think this idea is now outdated (we know when we have a sort spec) and an exception should just be thrown on a syntax error. -Yonik On 6/21/07, J.J. Larrea <[EMAIL PROTECTED]> wrote:
Because "score desc" is the default Lucene & Solr behavior when no explicit sort is specified, QueryParsing.parseSort() returns a null sort so that the non-sort versions of the query execution routines get called. However the caller SolrPluginUtils.parseSort issues that warning whenever it gets a null sort. Perhaps that interaction should be altered, or perhaps it should be left in as a sort of "are you sure you want to tell me what I already know?", er, warning. But as it stands you can simply ignore it, or else leave the sort off entirely when it is "score desc"; if the behavior were different in those two cases it would certainly be a bug, but as you noted that's not the case. - J.J.

It does not seem that it should be there. But as I said, it does not appear to affect operation as the results are sorted by score descending anyway (because that is the default?).
