How to find the uncommon values of a field between two indexes?

[amaurya1]

I have two indexes "abc" and "def". There is a field in index "abc" ---> "operator_id".
Similarly, there is a field in index "def" --> "worker_id".

My end goal is to find out those operator_ids which are present only in index "abc".
In my below search, I'm first finding out the common values between worker_id and operator_id. And I'm getting the right result,
but then I'm trying to find ids in index "abc" by eliminating the common values between the two columns but I'm getting all the values present in "abc".

index=abc  work_status=1 
operator_id =* NOT
[search index=abc  work_status=1 

[search index=def 
|stats count by  worker_id | rename worker_id as operator_id | table operator_id]

|stats count  by  operator_id]
|stats count  by  operator_id

Hi amaurya1,
if you have few records in def index (less than 50,000) you could run something like this:

index=abc NOT [ search index=def | rename worker_id AS operator_id | fields operator_id ]
| ...

If instead you have more than 50,000 records in index def, you have to run something like this:

index=abc OR index=def
| eval operator_id=coalesce(operator_id,worker_id)
| stats values(index) AS index count BY operator_id
| search count=1 AND index=abc
| ...

Bye.
