How to search for string like "KeyError: 'ABC_DEF'"

[stevenfharris]

I am trying to search for log entries that contain the following: KeyError: 'ABC_DEF'

The following work, but will find all instances of ABC_DEF even if it is not accompanied by KeyError:

• ABC DEF
• ABC_DEF
• 'ABC_DEF'

The following return nothing of use to me:

• KeyError: ABC_DEF
• KeyError: 'ABC_DEF'
• KeyError ABC_DEF
• KeyError ABC DEF
• KeyError
• "KeyError:"

What should my search look like to find the above?

Of note, the last entry above would resolve to the following Splunk query string: index=* "KeyError:"

Thank you in advance

It isn't clear whether you have tried these strings in double quotes or not

index=* "KeyError: 'ABC_DEF'"
