Recency Boost on date field containing nulls

Elastic Search
1

Hi,
I have an issue with an App Search engine where I'm attempting to apply a recency boost on a date field. Some of the documents in the engine do not have values for the date field and they are boosted to the top of the results.

It appears that the null valued documents are defaulted with the current date/time for calculating the boost value.

Relevance Tuning for field
Boost
Function: Linear
Center: now
Impact: 9.3

Is there a way to prevent documents without a date from being boosted as if they had today's date?

Hi @Brad_Hall

Unfortunately its not possible to do this and requires all documents to have the field value. Not a great option but could you index each null field with a default baseline date?
