Hello @vikas4cloud
If you're using KQL, you should be able to search:
kubernetes.namespace_name.keyword : dev and kubernetes.pod_name.keyword : dev-web*
If you're using Lucene search, you should be able to use:
kubernetes.namespace_name.keyword:dev AND kubernetes.pod_name.keyword:dev-web*
From the field names, I can see you are not using the Index Templates provided with Filebeat to ingest Kubernetes logs.
This is an example on our demo data
