How to reuse same Nest client Elastic Search, but have all indices injected when declaring the client

I have 3 indices in Elastic Search and I will be querying them one at a time (meaning - I want results from only 1 index at any moment). How to declare ElasticSearch client and reuse?

Adding index name in the SearchRequest doesn't look like an option because when I don't give any default index name when initiating the client, it gives exception. Adding code below, any help is appreciated.

string cloudid = "something";
            var credentials = new BasicAuthenticationCredentials("something", "something");
            var connectionPool = new CloudConnectionPool(cloudid, credentials);
            var settings = new ConnectionSettings(connectionPool);
            var client = new ElasticClient(settings); //EXCEPTION HERE THAT - Index Name is NULL

ISearchRequest searchRequest = new SearchRequest("indexname")
            {
                Query = new TermQuery { Field = Infer.Field<Doctor>(d => d.FirstName), Value = "FirstName73069" }, 
                Size = 10000
            };

            var secondSearchResponse = await client.SearchAsync<Doctor>(searchRequest);

This is the code I have and it breaks at line 5(added comment). Note: I have to use SearchRequest object for my use case. Please suggest accordingly.

using Nest 7.17.4 version.

Default index name is used when when no other index name can be resolved for a request.

If you want to map different CLR types to different indexes while creating connection, you can use DefaultMappingFor

new ConnectionSettings()
.DefaultIndex("defaultindex")
.DefaultMappingFor<Index1>(m => m.IndexName("index1"))
.DefaultMappingFor<Index2>(m => m.IndexName("index2"))

Above query defines default index as "defaultindex" and respective indexes for models Index1 and Index2

On using new SearchRequest() , request will be queried against "index1" , inferred from settings.

You can also specify index name as SearchRequest("index1")
