Commands: head

Use: Returns the first N number of specified results in search order. This means the most recent N events for a historical search, or the first N captured events for a real-time search. The search results are limited to the first results in search order.

There are two types of limits that can be applied: an absolute number of results, or an expression where all results are returned until the expression becomes false.

If no options or limits are explicitly stated, the head command returns the first 10 results.
