[Hibernate Search] Problem when sorting by date

fabreax · **Posted:** Thu Jun 28, 2007 4:36 am

Hello,

I have a field date :

Quote:

@Field(index=Index.TOKENIZED, store=Store.YES)
@DateBridge(resolution=Resolution.SECOND)
private Date date;

For exemple, if I insert 2 values, in my lucene Indexes, I have :

and

When I made a sort by "titre", there is no problem.

When I made a sort by date or reverse date :
fullTextQuery.setSort(new Sort("date",false));
fullTextQuery.setSort(new Sort("date",true));
the result is the same !

Thank you

At least the field should not be tokenized

Yes, now, it is UN_TOKENIZED, but there is the same problem. I will see later ... hollydays ;)

Thank you for all Emmanuel.

Back from hollydays ...

My Entite class :

Code:

@Indexed
public class Entite
{
   @DocumentId
   private Integer id;

   @Field(index=Index.TOKENIZED, store=Store.YES)
   private String titre;

   @Field(index=Index.UN_TOKENIZED, store=Store.YES)
   @Transient
   @SuppressWarnings("unused")
   private String titreSort;

   @Field(index=Index.TOKENIZED, store=Store.YES)
   private String resume;

   @Field(index=Index.UN_TOKENIZED, store=Store.YES)
   @DateBridge(resolution=Resolution.SECOND)
   private Date date;

   ...
}

I inserted 2 objects and these are my indexes :

and

The result of

Code:

fullTextQuery.setSort(new Sort("date", false));

and

Code:

fullTextQuery.setSort(new Sort("date", true));

is the same :S

Well it works fine in the unit test suite.

It's a Lucene bug, thank you Emmanuel ;).

The solution is :
fullTextQuery.setSort(new Sort(new SortField( "date", SortField.STRING, true )));
