Why minimum_should_match does not return multiple match?

[Fosiul_Alam]

Hi All,

i am refering to this question How to use "OR" in Dev Tool Query While trying to extend this to 3 Match with a minimum should match number to 2 it does not return any when i set it like this ""minimum_should_match":1" its works, but only gives 1 match, but when i do like this ""minimum_should_match":2" then it does not return anything, where as i know the query should found minimum 2 match which are in the log

so what i am doing wrong ?
