There is not a lot of information here that will allow someone to help you. Please provide a more detailed description of what you are doing as well as a full reproduction script (data, mappings and queries) that can be run from the Kibana dev console.

I have 2 classes  
1.Student 2.Teacher  
Student class defination is  
public class Student  
{

```
  public long StudId { get; set; } 

  public string FirstName { get; set; }

  public string LastName { get; set; }

  public string Address { get; set; }

}

```

and Teacher class defination is  
public class Teacher  
{

```
    public long TeacherID { get; set; }

    public string FirstName { get; set; }

    public string Subject{ get; set; }

    public string Address { get; set; }

}

```

Student's data is stored in "student" index and Teacher's data is stored in "teacher" index. We are using NEST in c# and our search query looks like this

var searchResponse = elasticClient.Search(search =\> search  
.Index(new { "student","teacher"})  
.Size(searchRequest.pageSize)  
.From(searchRequest.index)  
.Query(query =\> query  
.MultiMatch(c =\> c  
.Fields(f =\> f.Field(searchFilter.field))  
.Query(searchFilter.value))));

in the searchResponse currently we are receiving Teacher's object but we need both Student and Teacher object how do we do that?? please help. Thank you.
