Which function would you use to combine multiple search results into one single table?

The function used to combine multiple search results into one single table is the join function. This is because the join function in Splunk allows you to merge records from two datasets based on a common field. This is particularly useful when you have two separate searches that retrieve related data, and you want to view this data together in a cohesive manner.

When you apply the join function, you specify the field that both datasets share, which enables the creation of a more comprehensive table that includes relevant information from both sources. As a result, you can analyze and compare data points that are linked together, which enhances the insights you can derive from your search results.

Other options serve different purposes; for example, the append command is used to add the results of one search to another without merging them based on a common field, while there isn't a function called combine in Splunk's SPL and merge typically refers to operations outside of a typical search context in Splunk. Therefore, join is the correct function for combining search results meaningfully into a single table based on matching fields.
