Suggestions response doesnt contain index information or information about document where the suggestion was found

Hi, I am trying to trace a suggestion to its source document returned by my search suggestion query in Elasticsearch 7.9

It seems the suggest Options only returns the suggested text , frequency and score. I see that the c# nest library i am using does support few other fields like index and context but they are always returned as null. Wanted to know if there is a way to enable these fields so that we can better trace from where a particular suggestion has been suggested.

Reason i want to do this is because my suggestion query is suggesting me a word that i cannot find in the general search query throughout my index so i want to make sure if the suggested word actually exists or is this a false record returned by the suggestions api.

I am searching the word purpoes which is a wrongly typed word for 'Purpose'

and i am getting a suggestion for the word 'Purpose' and 'Purpos' out of which the second word is no where to be found in my whole index.

Can i get any help on this issue please ?

Please note that version is EOL and no longer supported, you should be looking to upgrade as a matter of urgency.

That said, have you tried the explain endpoint?

Thanks for the reply. Yup i can upgrade soon.

and yes i tried to add explain in the suggest query but it only gives explanation for the main query results and nothing for the suggestions block.
