DocumentStatus

Where a document is in its lifecycle. Open: new values may be added. indexed, partially_indexed and failed are final.

A string. The SDKs keep a value they do not know yet as the string itself (Python: an unknown member carrying it), so a newer server never breaks an older SDK.

Value	Description
pending	Created; processing has not started.
processing	Being processed. stage says what the server is doing.
indexed	Searchable. Final.
partially_indexed	Searchable, but some enrichments did not complete; see partialFailures. Final.
failed	The document's content could not be processed. Final.
