Different order of results in DBpedia through SNORQL vs. SERVICE query

Question

I am trying to retrieve some data about movies from DBpedia. This is my query:

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX : <http://dbpedia.org/resource/>
PREFIX dbpedia2: <http://dbpedia.org/property/>
PREFIX dbpedia: <http://dbpedia.org/>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX onto: <http://dbpedia.org/ontology/>
PREFIX dcterms: <http://purl.org/dc/terms/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>

SELECT *
{{SELECT *

WHERE {
SERVICE<http://dbpedia.org/sparql>{
?movie dcterms:subject <http://dbpedia.org/resource/Category:American_films> ;
        a onto:Film ;
        rdfs:label ?title ;
        dbpedia2:gross ?revenue .

?movie onto:starring ?actorUri .
?actorUri rdfs:label ?actor .

OPTIONAL {
  ?movie onto:imdbId ?imdbId .
}
BIND(xsd:integer(?revenue) as ?intRevenue) .
FILTER ((datatype(?revenue) = 'http://dbpedia.org/datatype/usDollar') && (LANGMATCHES(LANG(?title), 'en')) && (LANGMATCHES(LANG(?actor), 'en'))) .
}
}
}}
ORDER BY DESC (?intRevenue)
LIMIT 40000
OFFSET 0

Running this query on http://dbpedia.org/snorql/ (without the SERVICE keyword) returns the correct result. However, doing so from a third party triplestore doesn't yield the same order (ex: Hobbit and Lord of the Rings are missing).

What do I need to change in the query to get identical results?

Answer 1

The best way to overcome this specific limitation is to have your own DBpedia mirror, on which you can set your own limits (including none), and which you can then use as either your primary or remote data store and/or query engine.

(ObDisclaimer: OpenLink Software provides the public DBpedia SPARQL endpoint, produces Virtuoso and the DBpedia Mirror AMI, and employs me.)
