When I call delete_by_query with ?refresh=wait_for, got this warning:
_delete_by_query/?refresh=wait_for] returned 1 warnings: [299 Elasticsearch-5.4.1-2cfe0df "Expected a boolean [true/false] for request parameter [refresh] but got [wait_for]
Is it supported?, doc's says it is.
And when I call delete_by_query with ?retry_on_conflict=3
It fails - invalid parameter.
I wanted to use these since when I delete records I got them rejected b/c of version conflicts. I read about ?conflicts=proceed but I am not sure if it will cause deleted records to remain. That's why I wanted to add retry first and then wait for.
