Hi, You can use the filter option provided by Kibana. You can filter the search results to display only those documents that contain a particular value in a field. You can also create negative filters that exclude documents that contain the specified field value. More can be read and understood here: [https://www.elastic.co/guide/en/kibana/current/field-filter.html](https://www.elastic.co/guide/en/kibana/current/field-filter.html) Thanks Rashmi ---
