The statement is correct. In Splunk's Search Processing Language (SPL), field names are case-sensitive, meaning that host and Host are treated as two different fields. Conversely, field values are case-insensitive by default during a search. For example, a search for user="admin" will match events containing user=admin, user=Admin, or user=ADMIN. While case-sensitivity for values can be enforced with specific commands or functions (e.g., case()), the default behavior is case-insensitivity.

The "False" option is incorrect because the statement accurately describes the default and fundamental behavior of case sensitivity in Splunk searches. Confusing the rules for field names and field values is a common mistake, but the official documentation is explicit. Field names are always case-sensitive, and field values are case-insensitive by default.

Search Manual

Version 9.2.1

"Search fundamentals": In the section titled "Case sensitivity

" the documentation states

"When you search

keep in mind that: Field names are case sensitive. For example

sourcetype is not the same as sourceType. Field values are not case sensitive. For example

GET is the same as get."

Search Reference

Version 9.2.1

"search command": Under the "Syntax" section for field-value pairing (=)

the documentation on value matching implicitly supports this. The description of how values are matched confirms that

unless a case-sensitive function is used

string comparisons are case-insensitive. For example

it notes that search "error" will match "error"

"Error"

and "ERROR".
