elasty | A research-oriented elastic body simulator

I am searching json file using elastic search. I inserted the data. Now I want to incorporate some conditions in DSL query. I have to incorporate

1) basic fuzziness like case and punctuation insensitive and forgive minor spelling mistakes in prefix matching

2) If a search text contains 3+ characters, I should return all search queries that are atmost 2 edit distance away from search text.

I am doing this second condition and I am facing difficulty in writing a query which satisfies both the conditions. Could anyone tell how to write a query? Below is the code written so far
