Hi Thomas
Yes, those forms of queries where causing the problem which was an
issue in the Virtuoso Server and has now been fixed.
SCORE_LIMIT is not supported in the Virtuoso SPARQL implementation or
the SPARQL specification itself from what I can see, but is an
extension we shall consider adding at some point.

Hi,
Great, it works - and is very fast, too!
Did these queries really cause the problems?
Is it also possible to use SCORE_LIMIT in SPARQL queries like mine?
If yes, can you give me an example, I don't know how the syntax for
that should look and what the upper and lower limits for the value is.
Regards,
Thomas

Hello!
MacTed asked me on #semsol to submit my dbpedia SPARQL queries
here, because maybe they are somehow connected to the problem of
dbpedia going down very often after your recent upgrade.
I use your web interface for some very harmless queries, but
maybe there is a problem with virtuoso's full text indexing
extension, as every time I use bif:contains in a query, dbpedia
is immediately gone afterwards.
The query in question is always like this:
prefix dbpedia2: <http://dbpedia.org/property/>
prefix foaf: <http://xmlns.com/foaf/0.1/>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?entity ?abstract WHERE {
?entity dbpedia2:abstract ?abstract .
?entity rdfs:label ?label .
?label bif:contains "'Ludwig Wittgenstein*'" .
FILTER (lang(?abstract )='de') .
}
LIMIT 20
Best regards,
Thomas
