Description Aristide 2013-05-06 07:53:55 UTC 
When I type nepomuksearch:/mimetype:image, or, nepomuksearch:/mimetype:pdf its work. Dolphin display all indexed pictures on first URL and all indexed pdf on second URL. 

But when I try to type : « nepomuksearch:/mimetype:image OR mimetype:pdf » I don't have results in Dolphin. Its a same problem when I mix mimetype with hastag or other.

Reproducible: Always

Steps to Reproduce:
1. Open dolphin
2. CTRL+L
3. Type « nepomuksearch:/mimetype:pdf OR mimetype:image
Comment 1 Ignacio Serantes 2013-05-06 08:26:10 UTC 
The query generated for  "mimetype:pdf or mimetype:jpeg" is:


select distinct ?r
where {
 {
  ?r <http://www.semanticdesktop.org/ontologies/2007/01/19/nie#mimeType> ?v1 . FILTER(bif:contains(?v1, "'pdf'")) .
 } UNION {
  ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#contentMimeType> ?v2 . FILTER(bif:contains(?v2, "'pdf'")) .
 } UNION {
 FILTER(bif:contains(?v1, "'jpeg'")) .
 } UNION {
 FILTER(bif:contains(?v2, "'jpeg'")) .
 } .
 
}

The right query must be:

SELECT DISTINCT ?r
WHERE {
  {
    {
      ?r <http://www.semanticdesktop.org/ontologies/2007/01/19/nie#mimeType> ?v1 . FILTER(bif:contains(?v1, "'pdf'")) .
    } UNION {
      ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#contentMimeType> ?v2 . FILTER(bif:contains(?v2, "'pdf'")) .
    }
  } UNION {
    {
      ?r <http://www.semanticdesktop.org/ontologies/2007/01/19/nie#mimeType> ?v1 . FILTER(bif:contains(?v1, "'jpeg'")) .
    } UNION {
      ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#contentMimeType> ?v2 . FILTER(bif:contains(?v2, "'jpeg'")) .
    }
  } .
 
}

QueryLib: Remove optimizations on group terms

This isn't a proper fix, but more like a temporary patch, which I should
find a proper way to fix in the future.
