How to implement analyzer?

Elastic Stack Elasticsearch
1

I configured analyzer in elasticsearch.yml with below define
configuration :

index :
analysis :
analyzer :
default :
tokenizer:lowercase

After the setting I searched the string "r*" which gives me the doc
which contains Rahul and ramesh.
Then I searched for "R*" This gave me the 0 hit.

I want to analyzed the querystring text with following settings.I
have confusion regarding,using analyzer in index.

How are you searching?

It sounds like you're doing a term search, not a query string search
