How do you evaluate the difference between 2 multivalue fields?

Hi,

Let's say we have 2 multivalue fields

Field1={a,b,c,d}
Field2={a,b,c,d,e}

Is it possible to evaluate the difference between these fields and display the additional value of Field2? So that Field3={e}

Best regards,

Heinz

Let me know what you think of the strategy:

| makeresults
| eval F1="a b c"
| makemv F1
| append
[| makeresults
| eval F2="a b c d"
| makemv F2 ]
| append [ | makeresults
| eval F2_Original="a b c d"
| makemv F2_Original ]
| stats values(F1) as F1, values(F2) as F2, values(F2_Original) as F2_Original
| mvexpand F2
| eval F3=if(F2 IN(F1),"",F2)
| fields F1, F2_Original, F3
| where len(F3)>0

The given information works, but I would consider something that is more direct:

Hi @HeinzWaescher

Try this and let me know

| makeresults 
| eval Field1="a,b,c,e", Field2="a,b,c,d" 
| eval Field3 =mvzip(Field1,Field2) 
| makemv delim="," Field3 
| stats list(Field1) as Field1,list(Field2) as Field2, count by Field3 
| mvcombine Field3 
| eval Field3=mvjoin(Field3,",") 
| where count=1 
| table Field1,Field2,Field3
