I've been experimenting a bit with queries that contain regular expressions and have noticed that they seem to be triggering 502 Bad Gateway errors. Or perhaps it's just a coincidence and there were other things going on around 10AM GMT?
Here's an example query where I'm looking for cities that start with "Silver": --- PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> SELECT ?s ?label WHERE { ?s wdt:P31 wd:Q515 . ?s rdfs:label ?label FILTER(regex(?label, "^Silver")) } LIMIT 15 --- Am I doing something wrong in the query? Occasionally it seems to work, but most of the time it waits for a while and then I get the 502 error. Any guidance you may have would be appreciated. //Ed
