This field set is meant to facilitate pivoting around a piece of data.
Some pieces of information can be seen in many places in an ECS event. To facilitate searching for them, store an array of all seen values to their corresponding field in related..
A concrete example is IP addresses, which can be under host, observer, source, destination, client, server, and network.forwarded_ip. If you append all IPs to related.ip, you can then search for a given IP trivially, no matter where it appeared, by querying related.ip:192.0.2.15.

| related.hash | All the hashes seen on your event. Populating this field, then using it to search for hashes can help in situations where you're unsure what the hash algorithm is (and therefore which key name to search). type: keyword Note: This field should contain an array of values.   Not applicable. |
