Hello,
The GUI of my SPARQL endpoint has a default query:
select distinct ?Concept where {[] a ?Concept} LIMIT 100
It is a useful query, but unfortunately it times out in my case. When
I lower the LIMIT number I do get a response. So there are two things
I would like to ask:
1. Is it possible to speed up the query, for example by having an
extra index (for rdf:type)?
2. Is it possible to change the default query somewhere?
The defaults are set in the [SPARQL] section of your Virtuoso instance
configuration file (i.e., the .ini file).
Thanks! Quite a logical place, actually.
Regards,
Frans
