When searching in Splunk, how are field values processed in relation to case sensitivity?

Field values in Splunk are processed in a case-sensitive manner by default. This means that when you conduct a search, the system distinguishes between different cases—such as "Error," "ERROR," and "error"—and treats them as distinct field values.

However, in cases where you need to perform a more flexible search, you have the option to use certain search commands or functions to handle case insensitivity. For example, applying the lower() function can normalize the text to lowercase, thus allowing for case-insensitive comparisons.

The choice stating that field values are never case sensitive does not accurately describe how Splunk processes its data and searches by default, which can lead to confusion when precise matching is required. Understanding this behavior is crucial for effective searching within Splunk, particularly when dealing with varied data inputs that could include case differences.
