I'm using a Gauss Decay function to decrease relevance of old documents in my index (origin is current time). Is there a way to prevent a Gauss function to return 0 for very old documents in this case?
I am using a function score query with score mode multiply. For very old documents in my index their relevance is always 0 because of multiplication with 0 from the Gauss Decay function with the current time as the origin. Is there a way to prevent this?
Thanks for your time, I appreciate any feedback
