As per the documentation, the rank feature query score is added to the overall query score.
Since the relevance score itself is not bounded - the actual store depends on the data in your indices - how do I make the rank feature score useful?
I'm trying to use a multi match query for relevance and using rank feature query to power ranking of results. However my multi match query score usually lies in the range 8 - 14. At this range even adding rank feature query score (which is in the range 0-1) is not really helpful.
Is there any way I can multiply relevance score with rank feature query score?
