I think my wikibase https://ottgaz.org, hosted on wikibase.cloud, needs to be reindexed. Certain SPARQL queries aren't working. More generally, I would like to understand how indexing works--is there a way to know when/if data is not indexed?
Steps to replicate the issue (include links if applicable):
My queries are not returning all the results I'd expect. For example, this query (meant to return all subregions of the superregion Q39) does not return https://ottgaz.org/wiki/Item:Q128, even though it has a status property object with the qualifier Q39.
query: # regions contained by Edirne (Q39)
PREFIX og: <https://ottgaz.org/entity/>
PREFIX ogs: <https://ottgaz.org/entity/statement/>

SELECT ?subregion ?subregionLabel ?statusLabel

?subregion ogp:P15 ?statement.
?statement ogps:P15 ?status.
?statement ogpq:P34 og:Q39.

}On Telegram, GreenReaper helped me with the following:
The ones that appear there were modified two days ago while the one that does not was only modified a week ago. Perhaps the indexing was not working properly at that time, in which case this is a Wikibase.cloud issue. I expect if modified it would start showing up.
I modified one item and it did indeed show up.
Later GreenReaper wrote
Not sure ?action=purge will do it. I think you might need to get the cloud team to reindex it. I think they have a method of doing it on their end.
Thanks for any specific and general advice. I'm hoping I don't have to request reindexing all that often--invisible data makes me nervous!
