Using the scan method: how to add preserve_order=True?

I need to scan through all the documents in a DocType, while preserving the order in which they were added to it.

I logically turned to the scan method, but that does not preserve the order. The elasticsearch-py scan helper method can take a preserve_order argument. But I can’t figure out how to use it with elasticsearch-dsl-py.

Is it possible?

@jaisharma639 regular sorting should work for you then: Search().sort('my_field').param(preserve_order=True).scan()

[honzakral]

You can do it by specifying params method, anything passed there will be used as a kwargs when calling the underlying method (client.search or, in this case, helpers.scan):

s = Search().params(preserve_order=True)
for d in s.scan(): print(d)

hope this helps.
