Are search terms case sensitive?

[darshyakmk]

What are the proper names for search terms and/or what does "search term" refer to? Is that case sensitive/insensitive? Can any one help on this?

A bit more about it at are search language keywords case-sensitive?

Search terms are not case sensitive, though field names are. A search like

sourcetype=WinEventLog error

That searches for a field named exactly sourcetype (it wouldn't match SourceType or SOURCETYPE, but will only match it if it's all lower case) for where the field sourcetype has a value of wineventlog. The wineventlog is not case sensitive, it's a search term, so wineventlog matches WinEventLog, wineventlog, or any other combination of upper and lowercase.

Ditto error. "Error" wasn't on the left hand side of an equals sign at any point like sourcetype was (which isn't a perfect rule, but usually works) so it's case insensitive. It'll match ERROR, error, Error, ERRor, errOr - anything with those 5 letters in a row, regardless of case.

Hope that helps, and happy Splunking!

Beware to eventtypes and tags that are case sensitive!
