Display the lowest duration for all models

[moinyuso96]

SerialNumber	Duration
111A	200
111A	500
2222	300
3333	100
3333	250

How can I display only the lowest duration for each SerialNumber.

 | dedup SerialNumber would sometimes get me the larger duration.

Expected Output:

SerialNumber	Duration
111A	200
2222	300
3333	100

Try

YOUR_SEARCH | stats min(Duration) as Duration by SerialNumber

My Sample Search :

| makeresults | eval _raw="SerialNumber	Duration
111A	200
111A	500
2222	300
3333	100
3333	250"| multikv forceheader=1 | stats min(Duration) as Duration by SerialNumber
