Heyy,

I have system where in the user lists some of his favourite teams and conferences and gives them a preference order lets say Team1 \> Team 2\> Team 3 and Conf1 \> Conf2 \> Conf 3 Let's call it user preferences order

Also I have multiple Indexes containing Teams, Conferences, Events(involving Teams), Shows(Talk shows abt Teams), Stations(podcasts, radio) which have their own preference order.

Based on the user preferences, I need to show the user most relevant data in accordance with the index preferences (Events\>Shows\>Stations\>Teams\>Conferences) (Let's say, System's Index Order)

Can I use Nested Function\_Score queries where in the inner query will query elasticsearch for the teams and conferences listed by the user according to his preference order and the outer function\_score query will have indices and type filters and adding boosts in accordance with proposed system's Index order.

function\_score{  
query : {  
function\_score:{}  
}  
functions : [  
filters, functions  
]  
}
