Elasticsearch search term for exact match does not work

Question

I use query_string to search. The search works fine, but getting all of the entries with lowercase and uppercase letters matches. But I want the exact match to be case sensitive? For example: Search field: "title" Current output:

• title
• Title
• TITLE

I want only first (title). How to solve this problem.

My code in java:

QueryBuilder qbString = null;

qbString = QueryBuilders.queryString ("name") field ("field_name") ;.

Answer 1

You need to configure the display / text processing so that the tokens are indexed without the bottom.
