fullTextQuery.getResultList().size() != fullTextQuery.getResultSize() when using criteria
-----------------------------------------------------------------------------------------
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
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

Hi Mathieu,
sorry it's not supported to mix Criteria restrictions and fullText restrictions
(there's a warning in the docs.. I'm thinking we should highlight that more).
What's the luceneQuery you're running in 3.2 ? from the result it looks like
you're running a MatchAllDocsQuery.

Hi Sanne,
Thanks for your answer.
I didn't find any mention of this in the documentation. I'll read it again.
Yes, I'm running a MatchAllDocsQuery. If it's not supported, I understand why the
method returns the total.

On [http://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/], paragraph
_5.1.3.4. Fetching strategy_ there's an "important" blue box highligthing
this text:
??Only fetch mode can be adjusted, refrain from applying any other restriction.??
I guess we need to be more explicit, and the method name was not the best.

---------------------------------------
You're right, I read it just after posting my previous comment.
I also read in the javadoc "No where restriction can be defined either".
However, I see I can use where restrictions : data returned by getResultList() seem
correct, am I wrong? The only problem seems the getResultSize() method.

-----------------------------------------
that's unexpected but interesting as you're not the first to ask for this
functionality.
Should be useful but was not intentional.. maybe due to some other recent change; would
you like to contribute some unit tests to verify this? In that case we could stop saying
it's not supported, and discuss if we should fix the getResultSize()
fullTextQuery.getResultList().size() != fullTextQuery.getResultSize()

Emmanuel Bernard commented on HSEARCH-753:
------------------------------------------
The major risk was that we could return null elements in a the getResultList() instead of
properly filtering results. If that has truly changed then we can:
* adjust the documentation still no recommending such use but letting people know that it
works ok except for getResultSize()
* we might even think about raising a exception when people use getResultSize on a
criteria with where clauses
fullTextQuery.getResultList().size() != fullTextQuery.getResultSize()

-------------------------------------------------------------------
The major risk was that we could return null elements in a the getResultList() instead of
properly filtering results. If that has truly changed then we can:
* adjust the documentation still no recommending such use but letting people know that it
works ok except for getResultSize()
* we might even think about:
** raising a exception when people use getResultSize on a criteria with where clauses AND
firstResult / maxResult is used
** return getResultList().size() if firstResult / maxResult is not used (that is
problematic though as it's way more costly than a Lucene size => probably not the
right thing to do

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
Fix For: 4.0.0.Alpha1
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

Thank you Mathieu and Julie. I have used your unit test and decided to raise an exception
if a Criteria query with restriction is used in conjunction with getResultSize()
