Slowlog not logging all queries

I have updated my indexing settings as follow:

    "": "0ms",
    "search.slowlog.threshold.query.debug": "50ms",
    "search.slowlog.threshold.query.warn" : "200s", 
    "search.slowlog.threshold.query.trace": "100ms",
    "search.slowlog.threshold.fetch.debug": "100ms", 

In my application, I am sending multiple requests. In my slowlog of the requests, I only see the last request but not the other previous ones. Does someone know how to log all requests in the slowlog?
