Evolve indexing on existing repository data [DATAREDIS-894]

Sayali opened DATAREDIS-894 and commented

I've below data in Redis and I've Address as model class which has two fields street and city. I've data which has @Indexed on street fields and redis only contains indexed data on street. Now, I want @Indexed to be applied on the data present in the Redis data. How can I do that ?
 

127.0.0.1:6379> KEYS *
 1) "employees:d15be3e8-7662-40bb-ac4e-7b000e6391ec"
 2) "employees:d15be3e8-7662-40bb-ac4e-7b000e6391ec:idx"
 3) "employees:id:d15be3e8-7662-40bb-ac4e-7b000e6391ec"
 4) "employees"
 5) "employees:addresses.street:ABC Street"
 6) "employees:addresses.street:XYZ Street"

In model class I applied @Indexed on city, now my modelled becomes like

Address.java

@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Address {
    @Indexed
    private String street;

    @Indexed
    private String city;
}

Employee.java

@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
@RedisHash("employees")
public class Employee {
    @Id @Indexed
    private String id;
    private String firstName;
    private String lastName;
    private List<Address> addresses;
}

Now, unless I don't put indexing on redis actual data, List<Employee> findByAddresses_City(String city); doesn't fetches the result.

How can I do that ? I cant wipe out the exsisting data and create new. Any quick help ?
