Eric Pugh commented on SOLR-9775:
---------------------------------
What if we change the logic in SolrIndexSearcher.java
key =
{color:#cc7832}new {color}QueryResultKey(q{color:#cc7832},
{color}cmd.getFilterList(){color:#cc7832}, {color}cmd.getSort(){color:#cc7832},
{color}flags{color:#cc7832}, {color}cmd.getMinExactCount())
So that Sort is never null and getFilterList is never null, and indeed, then
also purge any nulls in the sort fields and filterlist? That might simplify a
lot of the logic in QueryResultKey hashcode and equals methods.....
