Redash aggregation with Elastic Search



I am trying to pull data from elastic search and could pull data without aggregation. But when I do aggregation , the text is splitting wherever ‘-’ keyword is there. i tried to do non analyze but was not able to do.

Also i would like to know how to visualize this.

In the normal query without aggegation I can specify the size. But in aggregation query, even if I specify the siize I am getting only 10 records.
