[Nepomuk] Problem with nepomuksearch

[Peter Penz]

Hi,

I've recently adjusted Dolphin to use the new Nepomok Query API. I like the 
API very much, but there is one "minor" problem on my system: I don't get any 
search results :-(

I build the comparison term this way:

Nepomuk::Query::ComparisonTerm term(prop, literal, comp);

In my testcase the values are:
- prop: 
QUrl("http://www.semanticdesktop.org/ontologies/2007/08/15/nao#lastModified")
- literal:
[Literal "2009-01-01"^^<http://www.w3.org/2001/XMLSchema#date>]
- comp:
ComparisonTerm::GreaterOrEqual

The resulting term is:
 [<http://www.semanticdesktop.org/ontologies/2007/08/15/nao#lastModified> >= 
[Literal "2009-01-01"^^<http://www.w3.org/2001/XMLSchema#date>]]

This looks OK. Afterwards I'm doing something like this:

Nepomuk::Query::Query query;
query.setTerm(term);
KUrl url = query.toSearchUrl();

and url will be:
KUrl("nepomuksearch:/?sparql=select distinct ?r  where { ?r 
<http://www.semanticdesktop.org/ontologies/2007/08/15/nao#lastModified> 
"2009-01-01"^^<http://www.w3.org/2001/XMLSchema#date> .    }")

So it seems that the >= operator has been removed... I tried to add it 
manually, but also get no results... Since my update to Virtuoso also "hand 
made queries" like:

nepomuksearch:/tag:TestTag1

don't give a result, although there is a tagged file with this tag (see 
http://enzosworld.gmxhome.de/temp/search1.png and 
http://enzosworld.gmxhome.de/temp/search2.png). At least just listing the tag 
works: http://enzosworld.gmxhome.de/temp/search3.png

Any hints would be very welcome! Thanks,
Peter
