Raise exception when there is a risk of having fullTextQuery.getResultList().size() != fullTextQuery.getResultSize() -------------------------------------------------------------------------------------------------------------------- Key: HSEARCH-753 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-753 Project: Hibernate Search Issue Type: Bug Components: query Affects Versions: 3.4.0.Final Environment: hibernate 3.6.4.Final / postgresSQL Reporter: Mathieu Perez Assignee: Emmanuel Bernard Fix For: 4.0.0.Alpha2 Attachments: ResultSizeOnCriteria.java, Tractor.java 1) My indexes are up-to-date and optimised 2) I'm aware about this part of documentation: "Like Google, the number of results is approximative if the index is not fully up-to-date with the database (asynchronous cluster for example)." 3) Two types of queries: 3.1) Query with "keyword" (or "below"/"above"/"fromTo") {code} QueryBuilder qb = fullTextSession.getSearchFactory().buildQueryBuilder().forEntity( Book.class ).get(); org.apache.lucene.search.Query query = qb .keyword() .onFields("title", "subtitle", "authors.name", "publicationDate") .matching("Java rocks!"); .createQuery(); {code} In this case, I don't meet any problem: query.getResultSize() == query.getResultList().size() 3.2) Query with criteria {code} Criteria criteria = s.createCriteria( Book.class ).createCriteria('isbn').add(Restrictions.like('XXXXXX')) Query q = s.createFullTextQuery( luceneQuery ).setCriteriaQuery( criteria ); {code} In this case, the result is different: {code} query.getResultSize() != query.getResultList().size() {code} Actually, query.getResultSize() exactly returns the number of Book contained in my Book's table. (select count(*) from Book;) without taking in consideration my criteria. I don't known if it's really a bug either it's the expected behaviour. When inspecting the org.hibernate.search.query.engine.impl.HSQueryImpl java class, I realized that {code} QueryHits queryHits = getQueryHits( searcher, 0 ) : {code} - 3.1) Takes in charge my keyword - 3.2) Doesn't seem to use my criteria
