Multiple index combined boost using boost query

[Gajjar, Jigar]

Hi All,


I want to apply multiple Index combined boost.

if(query({!terms f=au v='living' cache=false}),10.0,1) AND if(query({!terms 
f=ti v='living' cache=false}),10.0,1)

My requirement is, if my term ‘living’ matching both field au and ti both in 
same document then only add a boost to record.

Can anyone help my providing correct way to writing such boost query.

Thanks,
Jigar Gajjar
