[Nepomuk] (Wrong) Query result count

[François]

Hi guys,

I'm sorry to bump this thread up but I'm still encountering that weird thing :
when I run my query, I never get the same results :(


Here is some code (Python) :

c = Nepomuk.Types.Class(OntologiesUrls.movieType())      #c = NMM::Movie
self.resourceTypeTerm = Nepomuk.Query.ResourceTypeTerm(c)

self.query = Nepomuk.Query.FileQuery(self.resourceTypeTerm)
self.query.addIncludeFolder(somePath, True)

myModel.dirLister().openUrl(self.query.toSearchUrl()) # myModel.dirLister() is 
a KDirLister instance)


Here is the resulting Sparql query :

select distinct ?r where { { ?r a 
<http://www.semanticdesktop.org/ontologies/2009/02/19/nmm#Movie> . ?r a ?v1 . 
FILTER(?v1 in 
(<http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#Folder>,<http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#FileDataObject>)) 
. ?r <http://www.semanticdesktop.org/ontologies/2007/01/19/nie#url> ?v2 . 
FILTER(REGEX(STR(?v2), '(^file:///home/shared/Films/)', 'i')) . } . }


As in october, the exact same query in NepoSak gives the expected result.

I'll be glad to provide whatever you may need (code, logs,..) :)

Cheers,
