derivedStructData

object (Struct format)

Output only. This field is OUTPUT_ONLY. It contains derived data that are not in the original input document.
indexTime

string (Timestamp format)

Output only. The last time the document was indexed. If this field is set, the document could be returned in search results.

indexStatus

object (IndexStatus)

Output only. The index status of the document.

  • If document is indexed successfully, the indexTime field is populated.
  • Otherwise, if document is not indexed due to errors, the errorSamples field is populated.
  • Otherwise, if document's index is in progress, the pendingMessage field is populated.
