Hibernate Search indexing field ignoring characters ordering

Hi all,

I was wondering if there is any way of indexing a field without some characters that i do not want to index.

I have titles like these:

-The book of my life
-[book x]
-'book of my life'

And I have these titles indexed in a untokenized field. But what I want is to sort the results, it does not work because of the [ or ' characters. I would like to remove some of these characters (I have more, this is just an example) at the moment of indexing the entity.

Is there any way of doing this?

I could do it with java replace method but I don't think this is the best solution.

this is my entity code:

Code:

@Indexed
public class TituloEntity implements Serializable, Auditable 
{
   
   /** The Constant serialVersionUID. */
   private static final long serialVersionUID = 1L;

   /** The id titulo. */
   @DocumentId
   private int idTitulo;

   @Fields( {
       @Field(name = "titulo_untokenized", index = Index.UN_TOKENIZED),
       @Field(name = "titulo_untokenized_prueba", index = Index.UN_TOKENIZED, bridge = @FieldBridge(impl = TituloBridge.class)),
       @Field(name = "titulo", index = Index.TOKENIZED),
       @Field(name = "titulo_filter", analyzer=@Analyzer(definition="capsFilter"))
    } )
   private String titulo;

thanks everybody!

Hi, you could use an analyzer which strips out the custom tokens and sort on it.

Just make sure the output of such an analyzer is made of a single token: a field to be sorted on requires to be a single token or you get very strange reults.
