Hi folks

I want to find the largest documents in my indices and I have installed the mapper size plugin and added the field to index as it explained  
I have two questions now  
how to add it to index pattern in kibana?  
how to search large documents in kibana discovery? I can not see any parameter called \_size in kibana

[Using \_size in Kibana](https://www.elastic.co/guide/en/elasticsearch/plugins/master/mapper-size-usage.html)  
To use the \_size field in Kibana, update the metaFields setting and add \_size to the list of meta fields. metaFields can be configured in Kibana from the Advanced Settings page in Management.
