On bulk merge/upload, response should be 200 ok if document was successfully re-indexed
Azure search should respond back with success message on successful re-indexing of the merged\uploaded data as against current behavior which seems to indicate "Merge \Upload request is taken up and would be indexed after unknown time, please keep looking"..
Thank you for your feedback. We understand the value this would bring, but there is concern about keeping an update request open the entire time it takes to index everything contain within it. What we may consider here is an API to request the status of the indexing queue to determine what has/hasn’t been processed. We’d like to know if this would be useful to you.
While it is unlikely we’ll address this suggestion in the near future, we’ll reassess based on the number of votes it receives.
