No query registered for [match_none]

Tried searching but ironically there were no matches ...

Anyway, as of earlier today I've been seeing these errors logged by the hourly similar threads rebuild:

They've been logged in tandem seemingly for no obvious reason for the past several hours.

XF 2.2.6, XFES 2.2.1, ElasticSearch 2.4.2.

Nothing has knowingly changed, but hosting have said "match_none was not introduced until ES 5.x" - only reference I can see to it is inside XFES\Search\Source\Elasticsearch::getMLTSearchQueryDsl but these versions have been running without issue for some time now, so I have to assume it's something with the ES instance itself.

Any suggestions on what to look into here? Even a direct match Google search has no results for the exception message so a bit stumped.

I think this would imply the rebuild was enqueued for a thread where \XF\Search\Data\Thread::getIndexData returns null. Is there anything peculiar about the thread in question (5310431), such as not having a valid forum relation or being a redirect?

We should handle this better in Elasticsearch<5, though worth noting even 5.x is pretty ancient and XFES 2.3+ will require Elasticsearch v7.2+.

Ah I didn't notice the ID in there, it seems to be related to deleting a node and having a stale thread in the database, so that makes sense, thanks.
