I'm using the below post in Akana and it returns all records with a paymentReasonCode of 426 or 427.

"companyCode": ["10"],  
"customerNumber":["52526"],  
"searchString":["IN paymentReasonCode.keyword :426,427"]

Is there a way to code NOT IN so I get all records that are NOT 426 or NOT 427?\*\* I have tried these, but they are not working

"searchString":["NOT IN paymentReasonCode.keyword :426,427"],  
"searchString":["NOT IN paymentReasonCode.keyword :426,427"],

Hey @mfwstchas,

Can you confirm that your question pertains to the Elastic App Search product? [https://www.elastic.co/app-search/](https://www.elastic.co/app-search/).

If so, could you rephrase it? I am not sure I understand what you are asking.

Thank you,

Jason
