How to assign field name as primary key in kvstore lookup table

[hemalalli]

I need to insert some records to lookup table and make sure that the lookup table should not allow the duplicate insertion
I'm using service.request POST REST call to insert the records to the collection via Splunk HTML view.

NOTE: I don't want to use "dedup" to display, because I need to avoid insert if the lookup table has another record.

Please help !

I have implemented the workaround to avoid duplication while inserting to the KV store collection

Once the fields are entered in the splunk view, I'm running the search query and getting the key(_key) if the fields are matching in the KV store collection, if the key is available then I'm popping up the messaging saying "Record already exist", otherwise I'm inserting the record.
