elastic-builder: how to retrieve all unique value of one specific field


I am completely new using elastic search with current project(elastic-builder is used) and documentation of elastic-builder is bit confusing.
I need to retrieve all unique values of one specific field, say creator of tasks stored on server, how should I compose the query to achieve this?


You can use the terms aggregation to get all the unique values sorted by count from a field. If you use the default mapping for your index, your creator field should have a subfield creator.keyword that you can use for the terms aggregation.
