Hey @Roni_Saha, you can do this using Regular Expressions in Painless Scripted fields. However, this will be rather slow and resource intensive, and depending on the size of your data you might want to do so during index using Logstash.
I am aware of the "index using Logstash" that are suggested by you. But the problem is to define field during indexing is that I have thounds of such different patterns!
I will try REGEX and monitor the performance [ because in some cases Auto-Refresh would be 1-5 minutes ].
