Can you use multiple eval commands within a single search?

The ability to use multiple eval commands within a single search is indeed supported. Each eval command can create or modify fields in your dataset, and you can chain multiple eval statements together sequentially in a single search. This means that you can perform numerous calculations or transformations on your data as needed without the limitations that the incorrect options imply.

In a practical scenario, you might want to calculate several new fields based on different expressions. Using multiple eval commands allows you to handle this efficiently in a single pipeline, making it possible to refine and format your results all at once.

The other options suggest limitations that do not align with Splunk's capabilities for handling eval. For example, the idea of restricting eval to sub-searches or macros does not reflect its intended usage in searches. eval is a versatile command that can be applied multiple times within the same search context, enhancing its utility for data analysis.
