How to search for fields with empty values?

I'm trying unsuccessfully to select events with fields with empty values.

How can this be accomplished?

My events:

....|responseCode=F10|responseDesc=Invalid|status=SUCCESS|errorCode=0|errorDesc=No Error|
....|responseCode=G10|responseDesc=Invalid|status=SUCCESS|errorCode=0|errorDesc=|
....|responseCode=G12|responseDesc=Invalid|status=SUCCESS|errorCode=0|errorDesc=|

So I need to search the events with errorDesc='empty', like the last 2 events.

I tried the basic stuff, but no luck. Also len(errorDesc) doesn't consider the events.

I will appreciate any help/guidance.

No problemo @snemiro_514 At first I was thinking of the fillnull command too, but I figured there was definitely an easier method. Searched through some Answers posts and found it 🙂

Hi, yep!...that worked. I also have found a workaround...

index ... | fillnull value="XXX" responseDesc | search responseDesc="XXX"

Gracias!
