Hi, We are trying to messages based on ts-dt value in solr 6.2.1.
* One collection with only one shard, we are able to group ts-dt without error, but performance is getting worse over time * Multiple collections with only one shard each, we are able to group ts-dt without error for each collection shard, but performance is getting worse over time * One collection with multiple shards, we can't group ts-dt. Example error message" Error from server at http://xx.xx.xx.xx:8983/solr/test4s2rf_shard4_replica2: Invalid Date String:'Tue Sep 06 02:53:00 UTC 2016'" . In the error message, the Date string is not in the format that we write into solr, enhance we can't find it in solr. And every time we do grouping, the error message is different, for instance we run grouping second time, error could be "Error from server at http://xx.xx.xx.xx:8983/solr/test4s2rf_shard1_replica1: Invalid Date String:'Tue Aug 02 03:42:03 UTC 2016'" Has anyone had similar problem? Where could be the place we did wrong? Br, Xiao
