I have a Keyword field that don't have any analyzers. I want to use query_string query to do a case insensitive search on that field.
"name":"Mary Johnosn" is indexed into elastic and name is a keyword field. I am using query_string query with query attribute as "query":"(mar)" so that it has to check and return the names containing mar at any position and want to do case insentive search.
I am using query_String because I want to search on multiple fileds and use "query":"(mar)".
Can we do something during query_string to match keyword field in case insensitive way?
I want to do the same case insensitive search by using fields attribute in query_string query. Please suggest
