Causes

Use the cause:[causename] parameter to search for activities with a specific non-player cause.

“Causes” are names of any non-player “actor” that initiated an activity.

For example when axolotls kill glow squid, the entity is glow_squid and the cause is axolotl.

A search for cause:axolotl will return mobs killed by an axolotl.

A search for cause:lava will return a lot of bat deaths.

“Cause Names” will usually be block or entity names, or “environment”, but may include other things.

Players are a special kind of cause. To search for player-caused activities see player.
