@Indexed(SchemaFieldType.NESTED) does not work for JSONArray or List<Model> data types.

Document class -

@Data
@RequiredArgsConstructor(staticName = "of")
@AllArgsConstructor(access = AccessLevel.PROTECTED)
@Document(value = "cmpny:")
@IndexingOptions(indexName = "idx:company", creationMode = IndexCreationMode.DROP_AND_RECREATE)
class Company {
  @Id
  private String id;

  @Indexed(schemaFieldType = SchemaFieldType.TAG, sortable = true)
  private Set<String> tags = new HashSet<String>();

  /**
   * It does not creates the index on nested fields within Phones class.
   */
  @Indexed(schemaFieldType = SchemaFieldType.NESTED, sortable = false)
  private List<Phones> phonesList;

  // Below one works for nested fields within address.
  @Indexed(schemaFieldType = SchemaFieldType.NESTED, sortable = false)
  private Address address;
}

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Phones {

  @Indexed(schemaFieldType = SchemaFieldType.TAG, sortable = true)
  private String number;
}


@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Address {

  @Indexed(schemaFieldType = SchemaFieldType.TAG, sortable = true)
  private String city;

}

Upon executing with @EnableRedisDocumentRepositories(basePackages = "com.ecs.sgws.poc.romsdocuments.model"), it generates index for all fields except for List of Phones.

Below is the index info snapshot using FT.INFO idx:company

Expectation was to also get $.phonesList[*].number indexed but it did not get indexed. Right now we are defining schema in explicit manner (no declarative).

• redis-om-spring version : 0.9.5
• Followed reference document : https://redis.io/learn/develop/java/spring/redis-om/redis-om-spring-json

Please kindly add support for indexing json array kind of elements in declarative manner.

PS : Since json array is not supported in declarative manner, we also have a hunch that search result serialization might not also work with it, as see a similar code logic for projection fields - https://github.com/redis/redis-om-spring/blob/main/redis-om-spring/src/main/java/com/redis/om/spring/search/stream/SearchStreamImpl.java#L558

Please help in validating the mentioned behavior issue, fix can be prioritized later on.
