[jira] [Updated] (SOLR-6118) expand.sort doesn't work with function
queries
[ https://issues.apache.org/jira/browse/SOLR-6118?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Smiley updated SOLR-6118:
-------------------------------
Attachment: SOLR-6118_expand_sort_rewrite.patch
Simple fix w/ test. I think I've been bitten by this type of bug before -- forgetting to call:
{code:java}
if (sort != null)
sort = sort.rewrite(searcher);
{code}
It'd be nice if somehow Lucene's Sort.java maintained a "rewritten" boolean flag so that a bug like this would have been caught earlier during development. Maybe that's the solution, maybe not.
I noticed some indentation/spacing problems in ExpandComponent.java. I'll fix them in a separate commit.
