How to make control visualization as not case sensitive

[Dan]

I am using Controls visualization options list in kibana.

If we search value in this visualization it is case sensitive...

How can I make this as not case sensitive..

I am using below query to get...

{"index":"logstah-","ignore_unavailable":true,"preference":1580986265583}
{"timeout":"30000ms","terminate_after":100000,"size":0,"aggs":{"termsAgg":{"terms":{"order":{"_count":"desc"},"field":"department.keyword","include":".00."}}},"_source":{"excludes":[]},"stored_fields":[""],"script_fields":{},"docvalue_fields":[{"field":"@timestamp","format":"date_time"},{"field":"accounting_date1","format":"date_time"},{"field":"accounting_date2","format":"date_time"},{"field":"invoice_date","format":"date_time"}],"query":{"bool":{"must":,"filter":,"should":,"must_not":}}}

How can I make this query to search all values independent of the case...

Whether or not the search is case sensitive depends on the used tokenizer during ingest. https://www.elastic.co/guide/en/elasticsearch/reference/current/configure-text-analysis.html explains how to customize your text analysis during ingest. Your pipeline should include the lowercase tokenizer: https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-lowercase-tokenfilter.html
