I'm looking to create a merge strategy for a custom QParserPlugin I have. The plugin works fine on collections with one shard. I was very surprised to see it throw an exception when I ran it against a sharded collection. So my question is a bit of a shot in the dark. I'll first note that the CollapsingQParserPlugin included with Solr works as expected on my test collection with two shards.
The NPE occurs in my DelegatingCollector's finish() method as it's setting the next doc base. It appears I have a null LeafReaderContext. Without knowing anything about my code, what is it about multiple shards that might throw off a collector like this? thanks! v5.2.1 -- View this message in context: http://lucene.472066.n3.nabble.com/AnalyticsQuery-fails-on-a-sharded-collection-tp4289274.html Sent from the Solr - User mailing list archive at Nabble.com.
