Appengine query returning no matching index - Objectify - google-app-engine

Question

I have some entities that I wish to do an ancestor query on and filter a parameter by the ">" operator.
The entity in question inherits another object(I don't think this should matter). Below are my entity classes:
#Indexed
public class ValidatedObject {
public Long timeCreated=System.currentTimeMillis();
public Long timeUpdated=System.currentTimeMillis();
public Long getTimeUpdated() {
return timeUpdated;
}
public void setTimeUpdated(Long timeUpdated) {
this.timeUpdated = timeUpdated;
}
public Boolean validated=false;
#Unindexed
public String validatedID;
#Unindexed
private Long validatedTime;
#Unindexed
private String creatorID;
public Long getTimeCreated() {
return timeCreated;
}
public void setTimeCreated(Long timeCreated) {
this.timeCreated = timeCreated;
}
public boolean isValidated() {
return validated;
}
public void setValidated(boolean validated) {
this.validated = validated;
}
public String getValidatedID() {
return validatedID;
}
public void setValidatedID(String validatedID) {
this.validatedID = validatedID;
}
public Long getValidatedTime() {
return validatedTime;
}
public void setValidatedTime(Long validatedTime) {
this.validatedTime = validatedTime;
}
public String getCreatorID() {
return creatorID;
}
public void setCreatorID(String creatorID) {
this.creatorID = creatorID;
}
}
#Cached
#Entity
public class PersonnelInfo extends ValidatedObject{
#Id
public String keyName;
#Parent Key<Department> department;
private Long fdID;
#Unindexed
private String userKeyName;
private String firstName;
private String lastName;
#Unindexed
private String address,city,county,state;
#Unindexed
private String cellPhone,homePhone,otherPhone;
public PersonnelInfo(){
}
public PersonnelInfo(String email){
keyName=email;
}
#Override
public Long getTimeUpdated() {
return timeUpdated;
}
#Override
public void setTimeUpdated(Long time) {
timeUpdated=time;
}
}
My query code is as follows:
Query<PersonnelInfo> q = ofy.query(PersonnelInfo.class).ancestor(tmp).filter("timeUpdated >", lastSync);
I am getting the "no matching index found" error everytime. The query works fine without the filter. Some of the entities are missing the "timeUpdated" field because I changed the schema. There are some entities that have been created after the schema change with timeUpdated values and they are not returned. Also I can do a GQL query on the datastore viewer like this:
select * where FROM PersonnelInfo timeUpdated > 0
and I am returned entities, which makes me believe the index is created. What am I doing wrong here? Any help would be appreciated!

You need a multi-property index defined in your datastore-indexes.xml. It should be added to datastore-indexes-auto.xml when you run the query in dev mode, but the result should look like this:
<datastore-index kind="PersonnelInfo" ancestor="true">
<property name="timeUpdated" direction="asc"/>
</datastore-index>
