I'm really need your help i'm using Mongodb and hibernate OGM and i need quering a composite key using hibernate search but i'm getting an empty list=#000000]a date[/color].please help me here my code

person.java
@Entity
@Indexed
@Table(name = "souta")
public class Person {


@EmbeddedId
@DocumentId
@Field(index=Index.YES, analyze=Analyze.NO, store=Store.NO)
@FieldBridge(impl=PersonPkBridge.class)
private PersonPK idd;

@Column(name = "SURNAME", unique = true)
private String age;



public String getAge() {
return age;
}

public void setAge(String age) {
this.age = age;
}

public PersonPK getIdd() {
return idd;
}

public void setIdd(PersonPK idd) {
this.idd = idd;
}

personDAO.java

public List<Person> getMesureDate(Date datee) {


FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity(Person.class).get();
org.apache.lucene.search.Query query = queryBuilder.keyword().onField("idd.dat").ignoreFieldBridge().ignoreFieldBridge().ignoreFieldBridge().matching(datee).createQuery();

FullTextQuery fullTextQuery = fullTextEntityManager.createFullTextQuery(query, Person.class);

fullTextQuery.initializeObjectsWith(ObjectLookupMethod.SKIP, DatabaseRetrievalMethod.FIND_BY_ID);

List<Person> results = fullTextQuery.getResultList();
System.out.println("size of list");
System.out.println(results.size());

//System.out.println(results.get(0).getIdd().getDat());

return results;



}

PersonPK.java

@Embeddable
public class PersonPK implements Serializable{

@Field(index = Index.YES, analyze = Analyze.NO, store = Store.NO)
private int firstName;

@Field(index = Index.YES, analyze = Analyze.NO, store = Store.NO)
@DateBridge(resolution = Resolution.DAY)
@Temporal(javax.persistence.TemporalType.DATE)
private java.util.Date dat;

public java.util.Date getDat() {
return dat;
}
public void setDat(java.util.Date dat) {
this.dat = dat;
}
public int getFirstName() {
return firstName;
}
public void setFirstName(int firstName) {
this.firstName = firstName;
}


PersonPKBridge.java
public Object get(String name, Document document) {
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy", Locale.ENGLISH);
TimeZone utc = TimeZone.getTimeZone("UTC");
TimeZone.setDefault(utc);
PersonPK id = new PersonPK();

Field field = document.getField( name + ".firstName" );
id.setFirstName( Integer.parseInt(field.stringValue()) );
System.out.println( Integer.parseInt(field.stringValue()));
Field field3 = document.getField( name + ".dat" );

String dateInString = "Thu Apr 17 05:10:56 UTC 2014";
try {


id.setDat(sdf.parse(dateInString));

sdf.setTimeZone(utc);

} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return id;
}
public String objectToString(Object object) {
PersonPK id = (PersonPK) object;
StringBuilder sb = new StringBuilder();

sb.append( id.getFirstName() )
.append( " " )
.append( id.getDat() );
return sb.toString();
}
public void set(String name,
Object value,
Document document,
LuceneOptions luceneOptions) {
PersonPK id = (PersonPK) value;
Store store = luceneOptions.getStore();
Index index = luceneOptions.getIndex();
TermVector termVector = luceneOptions.getTermVector();
Float boost = luceneOptions.getBoost();
//store each property in a unique field

Field field = new Field( name + ".firstName",
String.valueOf(id.getFirstName()),
store, index, termVector );
field.setBoost( boost );
document.add( field );
field = new Field( name + ".dat",
String.valueOf(id.getDat()),
store, index, termVector );
field.setBoost( boost );
document.add( field );
//store the unique string representation in the named field
field = new Field( name,
objectToString( id ),
store, index, termVector );
field.setBoost( boost );
document.add( field ); }

Hi,
have you tried to use Luke http://code.google.com/p/luke/ to check if the content of the indexes is correct?

It is a bit hard to check the code like this, do you think you can create a test or save the java files somewhere I can download them?

Hi,
sorry I reply only now but I was on holiday this week with not much connectivity.

Thanks for the test, I've tried it and I've found something strange, it seems to me that you are saving the value "Sat Dec 17 05:10:56 UTC 1881" as date but you are looking for "Sat Dec 17 05:10:56 UTC 1880".

Also when you build the query you are looking for the keyword ignoring the field but not the analyzer, in the test case you are doing:

Code:
org.apache.lucene.search.Query query = queryBuilder.keyword().onField( "idd.dat" ).ignoreFieldBridge().matching( datee ).createQuery();


but I think it should be

Code:
org.apache.lucene.search.Query query = queryBuilder.keyword().onField( "idd.dat" )[b].ignoreAnalyzer()[/b].ignoreFieldBridge().matching( datee ).createQuery();

also when i want a time from intervall i get a list not correct.

here my function to get list date using above:

public List<Person> getMesureFromTO(Date debut) {


FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity(Person.class).get();
org.apache.lucene.search.Query query = queryBuilder.range().onField("idd.dat").ignoreAnalyzer().ignoreFieldBridge().above(debut).createQuery();

FullTextQuery fullTextQuery = fullTextEntityManager.createFullTextQuery(query, Person.class);

fullTextQuery.initializeObjectsWith(ObjectLookupMethod.SKIP, DatabaseRetrievalMethod.FIND_BY_ID);

List<Person> results = fullTextQuery.getResultList();
System.out.println("size of list par intervalle de date");
System.out.println(results.size());


return results;



}
