What is the maximum number of results that a subsearch can return?

The correct answer is that a subsearch can return a maximum of 10,000 results. This limit is significant because it helps manage performance and resource utilization when executing searches. Subsearches are typically used to filter the results of a primary search based on the results from another search. By limiting the number of results to 10,000, Splunk ensures that subsearches remain efficient and do not inadvertently overload the search process with excessive data.

This limit is particularly important for maintaining a balance in resource consumption and ensuring that the main query can process and utilize the results effectively. If the subsearch were allowed to return more than this limit, it may lead to increased search times and negatively impact the overall performance of the Splunk platform.
