I am writing a function in a function\_score query to alter the default  
score of a document based on the value of an attribute. For example, if an  
attribute "status" has two values "open" and "closed" and I want search  
hits with "open" status to be ranked higher than those with "closed"  
status.

My current idea is to scale the score of a search hit to a scale of 0 to  
(0.5_max\_score) for records with "closed" status and scale of  
(0.5_max\_score to max\_score) for records with "open" status. This will make  
open records to rank higher than closed records. This requires max\_score to  
be known in the function script.

Questions -

1. How to access max\_score of a search hit in the function script?
2. Is there an alternate way to achieve the above ranking?
