需要一个休眠搜索查询，如下面的条件查询：

public static List<EntityModel> getEntityJoin(Session session, String searchString) {

Criteria cri = session.createCriteria(EntityModel.class, "entity").createAlias
  ("entity.entityDetails","entityd").setFetchMode("EntityDetails", FetchMode.JOIN);

    Disjunction or = Restrictions.disjunction();
    or.add(Restrictions.like("entity.middle_name", "%"+searchString+"%"));
    or.add(Restrictions.like("entity.first_name", "%"+searchString+"%"));
    or.add(Restrictions.like("entity.last_name", "%"+searchString+"%"));
    or.add(Restrictions.like("entity.short_name", "%"+searchString+"%"));
    or.add( Restrictions.and(
            Restrictions.eq( "entityd.entity_attribute", "Entity Name"),
            Restrictions.like("entityd.attribute_value", "%"+searchString+"%")
        ) );
    cri.add(or);
    cri.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
    List<EntityModel> list = cri.list();
    return list;
}

这是基于条件的查询构建，我想要基于上述查询的休眠搜索查询。

Answer 1

首先，在@Field课程的entity_attribute上添加缺少的EntityDetails注释。根据您的查询，我假设您需要在此字段上进行完全匹配，因此您应该添加此注释：

  

@Field（name =“entity_attribute_unanalyzed”，analyze = Analyze.NO）

然后运行下一个查询（应该完成这项工作）：

FullTextSession fullTextSession = Search.getFullTextSession(session);
Transaction tx = fullTextSession.beginTransaction();
QueryBuilder qb = fullTextSession.getSearchFactory()
    .buildQueryBuilder().forEntity( EntityModel.class ).get();

//Create the main BooleanJunction
BooleanJunction bool = qb.bool();

bool.should(qb.keyword().onField("middle_name").matching(searchString).createQuery());
bool.should(qb.keyword().onField("first_name").matching(searchString).createQuery());
bool.should(qb.keyword().onField("last_name").matching(searchString).createQuery());
bool.should(qb.keyword().onField("short_name").matching(searchString).createQuery());

//create another BooleanJunction for the alias conjunction
BooleanJunction aliasBool = qb.bool();
aliasBool.must(qb.keyword().onField("entityDetails.entity_attribute_unanalyzed")
                           .matching("Entity Name").createQuery());
aliasBool.must(qb.keyword().onField("entityDetails.attribute_value")
                           .matching(searchString).createQuery());

//add the aliasBool to the main bool
bool.should(aliasBool.createQuery());

//execute query
org.apache.lucene.search.Query luceneQuery = bool.createQuery();
org.hibernate.Query hibQuery = fullTextSession.createFullTextQuery(luceneQuery , EntityModel.class);

// execute search
List<EntityModel> list = hibQuery.list();

tx.commit();
session.close();
