ElasticSearchCommitter said it committed documents but the index is empy

I am learning to configure and run the crawler and use ElasticSearchCommitter. I see the following in the logs:

Crawler_1: 2019-02-05 19:53:36 INFO - Sending 10 commit operations to Elasticsearch.
Crawler_1: 2019-02-05 19:53:36 INFO - Done sending commit operations to Elasticsearch.

Elastic logs don't have much:

[2019-02-05T19:48:46,711][INFO ][o.e.c.m.MetaDataCreateIndexService] [BiURPDs] [norconex] creating index, cause [auto(bulk api)], templates [], shards [5]/[1], mappings []
[2019-02-05T19:48:47,136][INFO ][o.e.c.m.MetaDataMappingService] [BiURPDs] [norconex/ojQVO0-gQQOvThpd7FPC-Q] create_mapping [web]
[2019-02-05T19:48:47,189][INFO ][o.e.c.m.MetaDataMappingService] [BiURPDs] [norconex/ojQVO0-gQQOvThpd7FPC-Q] update_mapping [web]

But the norconex index in elasticsearch is empty. I can see the index and its fields but it has no context.

Is there anything I am missing in my config or anything I need to configure on elastic end? It's pretty vanila installation, didn't change much in it.
