Re: Nested Document is flattened even with @Field(child = true) annotation
Wait, if I understand correctly, the documents would be indexed like that but we can get back the document as nested if we perform the blockjoinqueryparsing? So if I query normally with the default parser I would get all documents separately? Did i understand correctly?

Re: Nested Document is flattened even with @Field(child = true) annotation
Update,
I checked with the following example as well and this also flattens the
results.
I took the example from here -
https://issues.apache.org/jira/browse/SOLR-1945
package com.airplus.poc.edl.spark.auditeventindexer;
import java.io.IOException;
import org.apache.solr.client.solrj.SolrServerException;

public class SolrNestedTest {
public static void main(String[] args) throws IOException,
SolrServerException {
new SolrNestedTest().test();
}
public void test() throws IOException, SolrServerException {
String zkHostString = "host:2181/solr";
CloudSolrClient client = new CloudSolrClient(zkHostString);
Test test = new Test();
test.setId("2");
Child c = new Child();
c.child = true;
c.id = "1";
test.setChild(c);
client.addBean("event_store", test, 10);
client.close();
}
public class Child {
@Field
public String id;
@Field
public boolean child;
}
public class Test {
@Field
private String id;
@Field(child = true)
private Child child;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Child getChild() {
return child;
}
public void setChild(Child child) {
this.child = child;
}
}
}
The response back -

Nested Document is flattened even with @Field(child = true) annotation
I have the following structure for the class used for indexing a solr
document. I am using solrj 5.5.2 (same solr is being used on the cluster
with the collection in solr cloud mode having 3 shards)
I added the @Field(child = true) to the ChnagedAttribute object and even
though my document is indexed, it is flattened, such that, the object is
treated as a different document.
So rather than having 3 documents, I am getting 6 docs from solr when I
query for everything.
Any help regarding this issue is really appreciated.
@Data
public class EventDocument implements Serializable {
private static final long serialVersionUID = 1L;
@Field("id")
private String solrId;
@Field("eventName_t")
private String eventName;
@Field("Message_t")
private String message;
@Field(child = true)
private ChangedAttribute changedAttributes;
}
@Data
class ChangedAttribute implements Serializable {
private static final long serialVersionUID = 1L;
@Field("id")
private String id;
@Field("AttributeName_t")
private String attributeName;
@Field("OldValue_t")

@Field("NewValue_t")
private String newValue;
}
