When utilizing a subsearch within a Splunk SPL search query, which of the following statements...

Subsearches have a default result output limit of 10000. This means that a subsearch can return up to 10000 results to the main search. If the subsearch returns more than 10000 results, the main search will only use the first 10000 results and ignore the rest. This limit can be changed by using the maxout parameter of the format command or by setting the max_subsearch_results option in limits.conf. References:
