: LTR query throwing the following exception, what could be the reasons? It : is Solr 9.1.1
It means there is a really bad bug in Solr that the JVM is complaining about, and your data just happens to hit it ... but at a glance I'm not seeing any obvious problem with the code. (unless maybe the internal call to Float.compare() is returning Integer.MIN_VALUE and we're getting int rollover when it's negated?) Does this error reliably reproduce for you with a given query? with lots of queries? Are you familiar with how to build solr from source? If i gave you a patch that added a bunch of debug logging, would you be able to recompile solr and try the same query against the same data and put the (very verbose) debug logging up on a pastebin somewhere for review? -Hoss http://www.lucidworks.com/
