Elastic Client Search<T> method parsing problem

I use the Search method in the Elastic Client. If I give it as a search, I can pull data from Elastic. However, if I give it as Search, I can't pull data. All data comes in null. I arranged the inside of the CustomClass as it should be, but no matter what I did, I couldn't pull data from the CustomClass. When I pull it as Search, I can't filter properly. I leave the relevant code example below. Can you help?

This is example code

  var responseOis = this._elasticClient.Search<dynamic>(s => s
                .From(from)
                .Size(size)
                .Sort(k => k.Descending(new Field(sortField)))
                .Index(indexName)
                .Query(q => q.Bool(b => b.Must(mustClauses.ToArray())))
                .Query(q => q.Bool(b => b.MustNot(mustNotClauses.ToArray()))));

Elastic.Client ve Nest version 7.17

Since I thought there was no mapping to the data in the CustomClass, I arranged the fields according to the JSON returned from the elastic. However, it did not happen.

Solution

This problem is solved. Problem related to ElasticSearch boolean casting. Before, boolean values are 0 and 1. Then, this value convert true or false and problem is solved. In addition, there are 2 query bool in this code but in this time there is one query bool.
