I have a document like below -
Here items made nested in the mapings.
"shopName" : "royal super market",
Here i want to query on shopName , filter based on certain items and then score document based on geo and matched item names relevancy field.
I was hoping to push everything to functions in function score query.
But i cant seem to find anyway to get relevancy field value inside functions function of function_score.
Script does not seem to be able to pick values from inside nested object ( that is without touching _source )
Let me know if there is any method to do this ?
