After Integrating our existing Hibernate Search application with *ElasticSearch *, we are getting the following exception upon querying from created indexes :
java.lang.ClassCastException: Cannot cast org.hibernate.search.elasticsearch.analyzer.impl.ScopedElasticsearchAnalyzerReference to org.hibernate.search.analyzer.impl.LuceneAnalyzerReference
java.lang.Class.cast(Class.java:3369)
org.hibernate.search.analyzer.impl.RemoteAnalyzerReference.unwrap(RemoteAnalyzerReference.java:28)
org.hibernate.search.engine.impl.ImmutableSearchFactory.getAnalyzer(ImmutableSearchFactory.java:394)
org.hibernate.search.engine.impl.MutableSearchFactory.getAnalyzer(MutableSearchFactory.java:211)
org.hibernate.search.impl.SearchFactoryImpl.getAnalyzer(SearchFactoryImpl.java:53)
com.nucleus.controller.HibernateSearchController.search(HibernateSearchController.java:62)

The indexes were created successfully on ElasticSearch server. But when we try to query the indexes using the analyzer we get the above exception. The query is:

FullTextSession fullTextSession = org.hibernate.search.Search.getFullTextSession((Session) entityManager.getDelegate());
Analyzer analyzer = fullTextSession.getSearchFactory().getAnalyzer(AccountingStructure.class);
org.hibernate.search.jpa.FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search
.getFullTextEntityManager(entityManager);
org.apache.lucene.search.Query luceneQuery = MultiFieldQueryParser.parse(queryList, fieldList, analyzer);
