I am using query\_string for search. Searching is working fine but its getting all records with small letters and capital letters match.But i want to exact match with case sensitive?
For example :
Search field : "title"
Current output :

1. title
2. Title
3. TITLE,

I want to only first(title). How to resolved this issue.

My code in java :

QueryBuilder qbString=null;

qbString=QueryBuilders.queryString("title").field("field\_name");
