Perform search in Hibernate with specific analyzer

From http://hibernate.org/search/documentation/getting-started/#indexing

EntityManager em = entityManagerFactory.createEntityManager();
FullTextEntityManager fullTextEntityManager =
    org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
em.getTransaction().begin();

// create native Lucene query unsing the query DSL
// alternatively you can write the Lucene query using the Lucene query parser
// or the Lucene programmatic API. The Hibernate Search DSL is recommended though
QueryBuilder qb = fullTextEntityManager.getSearchFactory()
    .buildQueryBuilder().forEntity(Book.class).get();
org.apache.lucene.search.Query luceneQuery = qb
  .keyword()
  .onFields("title", "subtitle", "authors.name")
  .matching("Java rocks!")
  .createQuery();

// wrap Lucene query in a javax.persistence.Query
javax.persistence.Query jpaQuery =
    fullTextEntityManager.createFullTextQuery(luceneQuery, Book.class);

// execute search
List result = jpaQuery.getResultList();

How can I use a specific analyzer different then the one used on the fields or entities above search?

you can override the analyzer used for the specific field or fields in the following way

 QueryBuilder qb = fullTextEntityManager.getSearchFactory()
        .buildQueryBuilder().forEntity(Book.class)
        .overridesForField("title","analyzerName")
        .get();

Note : to override for multiple fields you can use the same call again since the overridesForField method returns an entityContext itself.

something like this

QueryBuilder qb = fullTextEntityManager.getSearchFactory()
            .buildQueryBuilder().forEntity(Book.class)
            .overridesForField("title","analyzerName")
            .overridesForField("subtitle","analyzerName2")
            .get();

Here is [the documentation](https://docs.jboss.org/hibernate/search/4.0/api/org/hibernate/search/query/dsl/EntityContext.html#overridesForField(java.lang.String, java.lang.String)).
