Can you think a way of trying to preview whether a query will return a huge
load of results?
I am trying to avoid timeout server errors.
As example a query like:
SELECT DISTINCT
COUNT(?entity)
WHERE {
VALUES ?entity_type {
dbpedia-owl:Person
dbpedia-owl:Organisation
dbpedia-owl:Place
}
?entity a ?entity_type ;
rdfs:label ?entity_label .
?entity_label bif:contains '"John*"' OPTION (score ?sc) .
FILTER(lang(?entity_label) = 'en')
}
is a possible candidate of this kind of error, so I would like to know
before hand its is better not to perform it.
Hope I was clear enough,
Thx,
Fernando
