This page describes the structure of the miniblocks index (Elasticsearch), and also depicts a few examples of how to query it.

The _id field of this index is represented by the miniblock hash, in a hexadecimal encoding.

Fields

Field	Description
senderShard	The senderShard field represents the shard ID of the source block.
receiverShard	The receiverShard field represents the shard ID of the destination block.
senderBlockHash	The senderBlockHash field represents the hash (hex encoded) of the source block in which the miniblock was included.
receiverBlockHash	The receiverBlockHash field represents the hash (hex encoded) of the destination block in which the miniblock was included.
type	The type field represents the type of the miniblock. It can be TxBlock (if it contains transactions) or SmartContractResultBlock (if it contains smart contracts results).
procTypeS	The procTypeS field represents the processing type at the source shard. It can be Normal or Scheduled.
