operations

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

_id​

The _id field of this index is represented by the transactions OR smart contract result hash, in a hexadecimal encoding.

Fields​

This index contains both transactions and smart contract results. This is useful because one can query both of them in a single request.

The unified structure will contain an extra field in order to be able to differentiate between them.

FieldDescription
typeIt can be normal in case of a transaction and unsigned in case of a smart contract result.
