Indexing and Searching with different analyzers

rusitoxx · **Joined:** Thu Jul 14, 2011 11:14 am **Posts:** 3

Hello, I'm new at the forum. I have to questions about this topic:

1.- Is there a simple way to index a list of entities using an specific analyzer with Hibernate Search? (different from the one specified at entity level)
2.- Can I create a QueryBuilder for an specific entity and using a specific analyzer? Using something like

Code:

queryBuilder.withAnalyzer(Analyzer)

Thanks in advance!
Regards,
Mariano.

Yes: http://docs.jboss.org/hibernate/stable/ ... e/#d0e3385

Yes, see the second code example:

Thank you for your response!

In relation with the second question, I was wondering If there is something like this or similar(using DSL):

Code:

QueryBuilder builder = ftSession.getSearchFactory().buildQueryBuilder()
            .forEntity( Empresa.class ).withAnalyzer(Analyzer).get();

As I read, the only way to override the "deafult" analyzer is using the overridesForField method. Is there something similar to the overridesForField method but at class level?

What I'm trying to do is the following:

I have an Empresa entity which I need to be indexed with a custom analyzer that for example doesn't have the SynonymFilter. But when I'm searching I want to use the other Analyzer (both at Entity level) that has the SynonymFilter. Is there a way to implement it without specifying each of the fields to override and using DSL?

ah, now I understand what you're trying to do. No I don't think there is one: would this be useful? I'm wondering, since when you're defining the query you still need to list the fields.
Can you post a better example to explain the use case?

Ok, this is part of the code when searching (the variable 'textoBusqueda' is the String that the user searched and 'fields' is an String[] with the indexed fields.):

Code:

         FullTextSession ftSession = getSesionBusqueda();
         Transaction tx = ftSession.beginTransaction();
        
         // creo el constructor de consultas DSL
         final QueryBuilder builder = ftSession.getSearchFactory().buildQueryBuilder()
            .forEntity( Empresa.class ).get();
      
         // creo la consulta de hibernate
         MustJunction query = builder.bool().must(builder.keyword().onField(ConstantesDTO.TABLA_EMPRESA_ESTADO).
                                 matching(EstadoEmpresa.PUBLICADA).createQuery());

                       //buscando el texto ingresado
                    if (StringUtils.isNotBlank(textoBusqueda)) {
                      query.must(builder.keyword().onFields(fields).matching(textoBusqueda).createQuery());
                    }

                         //creo busqueda con hibernate serarch para trar los resultados
                    hibQuery = ftSession.createFullTextQuery(query.createQuery(), Empresa.class);
                    hibQuery.initializeObjectsWith(ObjectLookupMethod.SECOND_LEVEL_CACHE, DatabaseRetrievalMethod.QUERY);

                        resultado.getEmpresas().addAll(hibQuery.list());

I tried to reduce the code in order to show only the query part.

thanks, almost clear now :)

Could you please open a JIRA request for this? https://hibernate.onjira.com/browse/HSEARCH

Also it doesn't seem hard: if you want to contribute it that would be nice.
