I need to search across multiple indices using OIS(Object Initializer Syntax). I have seen examples of executing search across multiple indices with Fluent DSL, but I still do not know how to execute an equivalent search with OIS.

Here is my OIS search(Only searching against one index) :

```
    var searchResult =
        await _client.LowLevel.SearchAsync<string>(ApplicationsIndexName, "application", new SearchRequest()
        {

            From = (query.PageSize * query.PageNumber) - query.PageSize,
            Size = query.PageSize,
            Query = GetQuery(query), 
            Aggregations = GetAggregations()
        });

```

Which modifications can be done, so I can search across multiple indices?
