HI @Harinder_Singh,

Welcome back. Setting fields names as case insensitive at query time isn't possible [as covered in this post](https://discuss.elastic.co/t/case-insensitive-search-on-fieldnames-not-values/87097). It would be best to normalise your field names to be consistent across all of your documents.

Are you using the [standard analyzer](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-standard-analyzer.html) on your documents? If so it makes use of a lowercase filter to convert text to all lowercase, giving you the case insensitive search you need on the values.

Hope that helps!
