+  - Adds `[@metadata][total_hits]` with total hits returned from the query ([#106](https://github.com/logstash-plugins/logstash-filter-elasticsearch/pull/106))
+  - Improves error logging to fully inspect caught exceptions ([#105](https://github.com/logstash-plugins/logstash-filter-elasticsearch/pull/105))

 ## 3.3.1
