On the following request elasticsearch crashes

curl -X GET "[http://localhost:9200/products/product/\_search](http://localhost:9200/products/product/_search)?  
pretty=true" -d '{"query":{"bool":{"must":[{"query\_string":  
{"query":"notebook"}}]}},"facets":{"categories":{"terms\_stats":  
{"key\_field":"category\_id","value\_script":"doc.score"}},"vendors":

{"key\_field":"vendor\_id","value\_script":"doc.score"}}},"size":10}'

[query\_fetch], total failure; shardFailures  
{IllegalArgumentException[Comparison method violates its general  
contract!]}]",  
"status" : 500
